We divide 86388249 by 748
We want to divide 86388249 by 748.

On to step 1:
748 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 748

On to step 2:
748 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 748

Going ahead to step 3:
When dividing 863 by 748, we get 1 with a remainder of 115.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 748 from 863 and we're left with 115.
Bring next digit (8) of the dividend behind the 115 and repeat the process: 1158 / 748

Step 4:
If we divide 1158 by 748, we get 1 and a remainder of 410.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 748 away from 1158, we end up with 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 748

Moving on to step 5:
748 can be fit into 4108 5 times, resulting in a remainder of 368.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we take 3740 away from 4108, we end up with 368.
Fetch the next digit (2) from the dividend, attach it to 368 and continue: 3682 / 748

Moving on to step 6:
The number 748 fits into 3682 4 times, leaving a remainder of 690.
Record the quotient 4 as the next digit in the result. 
Result so far: 1154.0
If we take 2992 away from 3682, we end up with 690.
Fetch the next digit (4) from the dividend, attach it to 690 and continue: 6904 / 748

Going ahead to step 7:
If we divide 6904 by 748, we get 9 and a remainder of 172.
Use 9 as the next digit of our solution. 
Result so far: 11549.0
Deduct 6732 from 6904 and we're left with 172.
Bring next digit (9) of the dividend behind the 172 and repeat the process: 1729 / 748

Step 8:
When dividing 1729 by 748, we get 2 with a remainder of 233.
Put 2 as the next digit of the answer. 
Result so far: 115492.0
The remainder is 233 after subtracting 1496 from 1729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 9:
748 goes into 2330 3 times with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 115492.3
Subtracting 2244 from 2330 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 10:
748 can be fit into 860 1 times, resulting in a remainder of 112.
The next digit of our result is 1. 
Result so far: 115492.31
If we take 748 away from 860, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 11:
If we divide 1120 by 748, we get 1 and a remainder of 372.
Put 1 as the next digit of the answer. 
Result so far: 115492.311
Deduct 748 from 1120 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final outcome is 115492.311, with a leftover of 0.0372.
