We look at the division of 13872765 by 921 
We want to figure out the number of times 13872765 can be divided by 921.

On to step 1:
If we divide 1 by 921, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 921

Moving on to step 2:
921 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 921

Going ahead to step 3:
If we divide 138 by 921, we get 0 and a remainder of 138.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 138 leaves us with 138.
Bring next digit (7) of the dividend behind the 138 and repeat the process: 1387 / 921

Step 4:
921 can be fit into 1387 1 times, resulting in a remainder of 466.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 921 from 1387 leaves us with 466.
Include the next digit (2) from the dividend after 466, then repeat: 4662 / 921

Step 5:
When dividing 4662 by 921, we get 5 with a remainder of 57.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 4605 from 4662 and we're left with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 921

Going ahead to step 6:
The number 921 fits into 577 0 times, leaving a remainder of 577.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 577 leaves us with 577.
Grab the next digit (6) from the dividend, add it to 577, then carry on: 5776 / 921

Going ahead to step 7:
921 can be fit into 5776 6 times, resulting in a remainder of 250.
The next digit of our result is 6. 
Result so far: 1506.0
Deduct 5526 from 5776 and we're left with 250.
Take the next digit (5) from the dividend and append it to 250, then repeat: 2505 / 921

Let's proceed to step 8:
If we divide 2505 by 921, we get 2 and a remainder of 663.
Put 2 as the next digit of the answer. 
Result so far: 15062.0
If we take 1842 away from 2505, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Advancing to step 9:
The number 921 fits into 6630 7 times, leaving a remainder of 183.
Write down 7 as next digit of the result. 
Result so far: 15062.7
The remainder is 183 after subtracting 6447 from 6630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 10:
If we divide 1830 by 921, we get 1 and a remainder of 909.
Use 1 as the next digit of our solution. 
Result so far: 15062.71
Subtract 921 from 1830 to get 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9090, and continue the process.

Moving on to step 11:
921 can be fit into 9090 9 times, resulting in a remainder of 801.
Record the quotient 9 as the next digit in the result. 
Result so far: 15062.719
Deduct 8289 from 9090 and we're left with 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

On to step 12:
When dividing 8010 by 921, we get 8 with a remainder of 642.
Use 8 as the next digit of our solution. 
Result so far: 15062.7198
Subtracting 7368 from 8010 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 13:
921 goes into 6420 6 times with a remainder of 894.
Use 6 as the next digit of our solution. 
Result so far: 15062.71986
The remainder is 894 after subtracting 5526 from 6420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

Let's proceed to step 14:
If we divide 8940 by 921, we get 9 and a remainder of 651.
Record the quotient 9 as the next digit in the result. 
Result so far: 15062.719869
The remainder is 651 after subtracting 8289 from 8940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Advancing to step 15:
If we divide 6510 by 921, we get 7 and a remainder of 63.
The next digit of our result is 7. 
Result so far: 15062.7198697
The remainder is 63 after subtracting 6447 from 6510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 16:
The number 921 fits into 630 0 times, leaving a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 15062.7198697
Deduct 0 from 630 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Our division results in 15062.7198697 with a remaining 6.3e-07.
