Let's divide 10126250 by 870
We want to divide 10126250 by 870.

Step 1:
1 divided by 870 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 870

Step 2:
870 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 870

Step 3:
870 can be fit into 101 0 times, resulting in a remainder of 101.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 101, we end up with 101.
Include the next digit (2) from the dividend after 101, then repeat: 1012 / 870

Let's proceed to step 4:
The number 870 fits into 1012 1 times, leaving a remainder of 142.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 870 from 1012 and we're left with 142.
Grab the next digit (6) from the dividend, add it to 142, then carry on: 1426 / 870

Advancing to step 5:
When dividing 1426 by 870, we get 1 with a remainder of 556.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 870 from 1426 to get 556.
Grab the next digit (2) from the dividend, add it to 556, then carry on: 5562 / 870

Advancing to step 6:
If we divide 5562 by 870, we get 6 and a remainder of 342.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 5220 away from 5562, we end up with 342.
Append the next digit (5) from the dividend to 342 and continue with: 3425 / 870

On to step 7:
3425 divided by 870 is 3 with a remainder of 815.
Use 3 as the next digit of our solution. 
Result so far: 1163.0
The remainder is 815 after subtracting 2610 from 3425.
Take the next digit (0) from the dividend and append it to 815, then repeat: 8150 / 870

On to step 8:
When dividing 8150 by 870, we get 9 with a remainder of 320.
The next digit of our result is 9. 
Result so far: 11639.0
If we take 7830 away from 8150, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 9:
The number 870 fits into 3200 3 times, leaving a remainder of 590.
The next digit of our result is 3. 
Result so far: 11639.3
Deduct 2610 from 3200 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 10:
870 goes into 5900 6 times with a remainder of 680.
Write down 6 as next digit of the result. 
Result so far: 11639.36
Subtract 5220 from 5900 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 11:
870 goes into 6800 7 times with a remainder of 710.
Use 7 as the next digit of our solution. 
Result so far: 11639.367
Subtracting 6090 from 6800 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 12:
The number 870 fits into 7100 8 times, leaving a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 11639.3678
Subtract 6960 from 7100 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
The number 870 fits into 1400 1 times, leaving a remainder of 530.
Write down 1 as next digit of the result. 
Result so far: 11639.36781
If we take 870 away from 1400, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 14:
The number 870 fits into 5300 6 times, leaving a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 11639.367816
If we subtract 5220 from 5300, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
The number 870 fits into 800 0 times, leaving a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 11639.367816
If we subtract 0 from 800, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 16:
870 goes into 8000 9 times with a remainder of 170.
The number 9 becomes the next digit in our result. 
Result so far: 11639.36781609
Subtract 7830 from 8000 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final result is 11639.36781609 with a remainder of 1.7e-07.
