We look at the division of 18639715 by 252 
We're looking to find how many times 252 goes into 18639715.

Going ahead to step 1:
If we divide 1 by 252, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 252

On to step 2:
The number 252 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 252

Advancing to step 3:
If we divide 186 by 252, we get 0 and a remainder of 186.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 186 to get 186.
Grab the next digit (3) from the dividend, add it to 186, then carry on: 1863 / 252

Moving on to step 4:
If we divide 1863 by 252, we get 7 and a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 1764 away from 1863, we end up with 99.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 252

Step 5:
The number 252 fits into 999 3 times, leaving a remainder of 243.
Use 3 as the next digit of our solution. 
Result so far: 73.0
The remainder is 243 after subtracting 756 from 999.
Grab the next digit (7) from the dividend, add it to 243, then carry on: 2437 / 252

Advancing to step 6:
When dividing 2437 by 252, we get 9 with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 739.0
Subtract 2268 from 2437 to get 169.
Grab the next digit (1) from the dividend, add it to 169, then carry on: 1691 / 252

Advancing to step 7:
1691 divided by 252 is 6 with a remainder of 179.
Write down 6 as next digit of the result. 
Result so far: 7396.0
If we take 1512 away from 1691, we end up with 179.
Grab the next digit (5) from the dividend, add it to 179, then carry on: 1795 / 252

Advancing to step 8:
The number 252 fits into 1795 7 times, leaving a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 73967.0
The remainder is 31 after subtracting 1764 from 1795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
252 goes into 310 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 73967.1
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
252 goes into 580 2 times with a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 73967.12
Subtracting 504 from 580 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
The number 252 fits into 760 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 73967.123
Subtracting 756 from 760 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 252 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 73967.123
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
If we divide 400 by 252, we get 1 and a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 73967.12301
Deduct 252 from 400 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 14:
252 can be fit into 1480 5 times, resulting in a remainder of 220.
The next digit of our result is 5. 
Result so far: 73967.123015
Deduct 1260 from 1480 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
When dividing 2200 by 252, we get 8 with a remainder of 184.
The next digit of our result is 8. 
Result so far: 73967.1230158
If we take 2016 away from 2200, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
1840 divided by 252 is 7 with a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 73967.12301587
If we subtract 1764 from 1840, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 73967.12301587, with a leftover of 7.6e-08.
