We're dividing 10250431 by 856 
Let's see how many times 856 fits into 10250431.

Let's proceed to step 1:
856 can be fit into 1 0 times, resulting in 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.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 856

Moving on to step 2:
856 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 856

Let's proceed to step 3:
856 can be fit into 102 0 times, resulting in a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 102 and we're left with 102.
Take the next digit (5) from the dividend and append it to 102, then repeat: 1025 / 856

Step 4:
If we divide 1025 by 856, we get 1 and a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 856 from 1025, we get 169.
Fetch the next digit (0) from the dividend, attach it to 169 and continue: 1690 / 856

Moving on to step 5:
If we divide 1690 by 856, we get 1 and a remainder of 834.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 856 from 1690 and we're left with 834.
Fetch the next digit (4) from the dividend, attach it to 834 and continue: 8344 / 856

On to step 6:
The number 856 fits into 8344 9 times, leaving a remainder of 640.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 7704 from 8344 leaves us with 640.
Include the next digit (3) from the dividend after 640, then repeat: 6403 / 856

Going ahead to step 7:
856 can be fit into 6403 7 times, resulting in a remainder of 411.
Use 7 as the next digit of our solution. 
Result so far: 1197.0
Subtracting 5992 from 6403 leaves us with 411.
Include the next digit (1) from the dividend after 411, then repeat: 4111 / 856

On to step 8:
The number 856 fits into 4111 4 times, leaving a remainder of 687.
The number 4 becomes the next digit in our result. 
Result so far: 11974.0
The remainder is 687 after subtracting 3424 from 4111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Going ahead to step 9:
856 can be fit into 6870 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 11974.8
The remainder is 22 after subtracting 6848 from 6870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
856 goes into 220 0 times with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 11974.8
Subtracting 0 from 220 leaves us 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 11:
2200 divided by 856 is 2 with a remainder of 488.
Write down 2 as next digit of the result. 
Result so far: 11974.802
Deduct 1712 from 2200 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
When dividing 4880 by 856, we get 5 with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 11974.8025
Subtract 4280 from 4880 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 13:
The number 856 fits into 6000 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 11974.80257
Deduct 5992 from 6000 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
The number 856 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 11974.80257
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
The number 856 fits into 800 0 times, leaving a remainder of 800.
Write down 0 as next digit of the result. 
Result so far: 11974.80257
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.

The final outcome is 11974.80257, with a leftover of 8e-06.
