Let's divide 15870406 by 750
Let's see how many times 750 fits into 15870406.

On to step 1:
The number 750 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 750

Moving on to step 2:
The number 750 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 750

Step 3:
If we divide 158 by 750, we get 0 and a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 158, we get 158.
Bring next digit (7) of the dividend behind the 158 and repeat the process: 1587 / 750

On to step 4:
750 goes into 1587 2 times with a remainder of 87.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1500 from 1587 and we're left with 87.
Fetch the next digit (0) from the dividend, attach it to 87 and continue: 870 / 750

Moving on to step 5:
750 goes into 870 1 times with a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 750 away from 870, we end up with 120.
Bring next digit (4) of the dividend behind the 120 and repeat the process: 1204 / 750

Let's proceed to step 6:
The number 750 fits into 1204 1 times, leaving a remainder of 454.
Put 1 as the next digit of the answer. 
Result so far: 211.0
If we take 750 away from 1204, we end up with 454.
Include the next digit (0) from the dividend after 454, then repeat: 4540 / 750

On to step 7:
750 can be fit into 4540 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 2116.0
If we subtract 4500 from 4540, we get 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 750

Step 8:
406 divided by 750 is 0 with a remainder of 406.
The number 0 becomes the next digit in our result. 
Result so far: 21160.0
Subtract 0 from 406 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 9:
4060 divided by 750 is 5 with a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 21160.5
The remainder is 310 after subtracting 3750 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
3100 divided by 750 is 4 with a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 21160.54
Subtract 3000 from 3100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
1000 divided by 750 is 1 with a remainder of 250.
The next digit of our result is 1. 
Result so far: 21160.541
Deduct 750 from 1000 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 12:
750 can be fit into 2500 3 times, resulting in a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 21160.5413
Deduct 2250 from 2500 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.

Going ahead to step 13:
750 goes into 2500 3 times with a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 21160.54133
The remainder is 250 after subtracting 2250 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 21160.54133, with a leftover of 0.00025.
