We're dividing 73864136 by 921 
Let's see how many times 921 fits into 73864136.

Advancing to step 1:
When dividing 7 by 921, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 921

On to step 2:
921 goes into 73 0 times with a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 921

On to step 3:
921 goes into 738 0 times with a remainder of 738.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 738 after subtracting 0 from 738.
Grab the next digit (6) from the dividend, add it to 738, then carry on: 7386 / 921

Advancing to step 4:
921 goes into 7386 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 7368 from 7386 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 921

Let's proceed to step 5:
If we divide 184 by 921, we get 0 and a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtract 0 from 184 to get 184.
Bring next digit (1) of the dividend behind the 184 and repeat the process: 1841 / 921

Step 6:
If we divide 1841 by 921, we get 1 and a remainder of 920.
Record the quotient 1 as the next digit in the result. 
Result so far: 801.0
If we subtract 921 from 1841, we get 920.
Grab the next digit (3) from the dividend, add it to 920, then carry on: 9203 / 921

Moving on to step 7:
When dividing 9203 by 921, we get 9 with a remainder of 914.
The next digit of our result is 9. 
Result so far: 8019.0
Subtract 8289 from 9203 to get 914.
Grab the next digit (6) from the dividend, add it to 914, then carry on: 9146 / 921

Advancing to step 8:
If we divide 9146 by 921, we get 9 and a remainder of 857.
The next digit of our result is 9. 
Result so far: 80199.0
Deduct 8289 from 9146 and we're left with 857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8570, and continue the process.

Going ahead to step 9:
921 goes into 8570 9 times with a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 80199.9
Subtract 8289 from 8570 to get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 10:
921 can be fit into 2810 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 80199.93
Subtract 2763 from 2810 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
921 can be fit into 470 0 times, resulting in a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 80199.93
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 12:
4700 divided by 921 is 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 80199.9305
Subtracting 4605 from 4700 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 13:
921 can be fit into 950 1 times, resulting in a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 80199.93051
Deduct 921 from 950 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 14:
290 divided by 921 is 0 with a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 80199.93051
Deduct 0 from 290 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 15:
When dividing 2900 by 921, we get 3 with a remainder of 137.
Put 3 as the next digit of the answer. 
Result so far: 80199.9305103
Subtract 2763 from 2900 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 16:
921 goes into 1370 1 times with a remainder of 449.
Put 1 as the next digit of the answer. 
Result so far: 80199.93051031
If we take 921 away from 1370, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

After the division, we end up with 80199.93051031 and a remainder of 4.49e-07.
