87051283 ÷ 252 
We want to divide 87051283 by 252.

On to step 1:
The number 252 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 252

Advancing to step 2:
252 goes into 87 0 times with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 252

Let's proceed to step 3:
252 goes into 870 3 times with a remainder of 114.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 756 from 870 to get 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 252

Advancing to step 4:
1145 divided by 252 is 4 with a remainder of 137.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 1008 away from 1145, we end up with 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 252

Step 5:
The number 252 fits into 1371 5 times, leaving a remainder of 111.
Use 5 as the next digit of our solution. 
Result so far: 345.0
Subtracting 1260 from 1371 leaves us with 111.
Grab the next digit (2) from the dividend, add it to 111, then carry on: 1112 / 252

Step 6:
1112 divided by 252 is 4 with a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 3454.0
Deduct 1008 from 1112 and we're left with 104.
Bring next digit (8) of the dividend behind the 104 and repeat the process: 1048 / 252

Moving on to step 7:
The number 252 fits into 1048 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 34544.0
Subtracting 1008 from 1048 leaves us with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 252

Going ahead to step 8:
The number 252 fits into 403 1 times, leaving a remainder of 151.
The number 1 becomes the next digit in our result. 
Result so far: 345441.0
Subtract 252 from 403 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 9:
252 goes into 1510 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 345441.5
Deduct 1260 from 1510 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
2500 divided by 252 is 9 with a remainder of 232.
Use 9 as the next digit of our solution. 
Result so far: 345441.59
The remainder is 232 after subtracting 2268 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
The number 252 fits into 2320 9 times, leaving a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 345441.599
Subtracting 2268 from 2320 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 345441.599, with a leftover of 0.0052.
