We're dividing 21031741 by 252 
We want to figure out the number of times 21031741 can be divided by 252.

Let's proceed to step 1:
The number 252 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 252

Going ahead to step 2:
If we divide 21 by 252, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 252

On to step 3:
210 divided by 252 is 0 with a remainder of 210.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 210, we get 210.
Include the next digit (3) from the dividend after 210, then repeat: 2103 / 252

On to step 4:
2103 divided by 252 is 8 with a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 87 after subtracting 2016 from 2103.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 252

Advancing to step 5:
871 divided by 252 is 3 with a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 756 from 871 and we're left with 115.
Grab the next digit (7) from the dividend, add it to 115, then carry on: 1157 / 252

Moving on to step 6:
When dividing 1157 by 252, we get 4 with a remainder of 149.
Put 4 as the next digit of the answer. 
Result so far: 834.0
Subtract 1008 from 1157 to get 149.
Take the next digit (4) from the dividend and append it to 149, then repeat: 1494 / 252

Advancing to step 7:
When dividing 1494 by 252, we get 5 with a remainder of 234.
Put 5 as the next digit of the answer. 
Result so far: 8345.0
Subtracting 1260 from 1494 leaves us with 234.
Fetch the next digit (1) from the dividend, attach it to 234 and continue: 2341 / 252

Step 8:
If we divide 2341 by 252, we get 9 and a remainder of 73.
Put 9 as the next digit of the answer. 
Result so far: 83459.0
The remainder is 73 after subtracting 2268 from 2341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
The number 252 fits into 730 2 times, leaving a remainder of 226.
Put 2 as the next digit of the answer. 
Result so far: 83459.2
Deduct 504 from 730 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 10:
2260 divided by 252 is 8 with a remainder of 244.
Use 8 as the next digit of our solution. 
Result so far: 83459.28
Subtracting 2016 from 2260 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 11:
2440 divided by 252 is 9 with a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 83459.289
The remainder is 172 after subtracting 2268 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 12:
The number 252 fits into 1720 6 times, leaving a remainder of 208.
Put 6 as the next digit of the answer. 
Result so far: 83459.2896
If we take 1512 away from 1720, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 13:
252 can be fit into 2080 8 times, resulting in a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 83459.28968
Subtracting 2016 from 2080 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
The number 252 fits into 640 2 times, leaving a remainder of 136.
Write down 2 as next digit of the result. 
Result so far: 83459.289682
The remainder is 136 after subtracting 504 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 15:
252 goes into 1360 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 83459.2896825
The remainder is 100 after subtracting 1260 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 16:
The number 252 fits into 1000 3 times, leaving a remainder of 244.
Use 3 as the next digit of our solution. 
Result so far: 83459.28968253
If we take 756 away from 1000, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The quotient of the division is 83459.28968253, and the remainder is 2.44e-07.
