We look at the division of 25496715 by 861 
Our goal is to divide 25496715 by 861.

Advancing to step 1:
861 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 861

Advancing to step 2:
When dividing 25 by 861, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 861

Advancing to step 3:
254 divided by 861 is 0 with a remainder of 254.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 254 leaves us with 254.
Append the next digit (9) from the dividend to 254 and continue with: 2549 / 861

Let's proceed to step 4:
If we divide 2549 by 861, we get 2 and a remainder of 827.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1722 from 2549 leaves us with 827.
Grab the next digit (6) from the dividend, add it to 827, then carry on: 8276 / 861

Going ahead to step 5:
8276 divided by 861 is 9 with a remainder of 527.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 7749 from 8276 and we're left with 527.
Bring next digit (7) of the dividend behind the 527 and repeat the process: 5277 / 861

Moving on to step 6:
5277 divided by 861 is 6 with a remainder of 111.
Write down 6 as next digit of the result. 
Result so far: 296.0
The remainder is 111 after subtracting 5166 from 5277.
Fetch the next digit (1) from the dividend, attach it to 111 and continue: 1111 / 861

Step 7:
If we divide 1111 by 861, we get 1 and a remainder of 250.
The next digit of our result is 1. 
Result so far: 2961.0
Subtracting 861 from 1111 leaves us with 250.
Fetch the next digit (5) from the dividend, attach it to 250 and continue: 2505 / 861

Step 8:
If we divide 2505 by 861, we get 2 and a remainder of 783.
Use 2 as the next digit of our solution. 
Result so far: 29612.0
If we take 1722 away from 2505, we end up with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Moving on to step 9:
7830 divided by 861 is 9 with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 29612.9
Deduct 7749 from 7830 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
810 divided by 861 is 0 with a remainder of 810.
The next digit of our result is 0. 
Result so far: 29612.9
Subtracting 0 from 810 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Advancing to step 11:
861 goes into 8100 9 times with a remainder of 351.
Use 9 as the next digit of our solution. 
Result so far: 29612.909
The remainder is 351 after subtracting 7749 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Step 12:
If we divide 3510 by 861, we get 4 and a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 29612.9094
The remainder is 66 after subtracting 3444 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
861 goes into 660 0 times with a remainder of 660.
The number 0 becomes the next digit in our result. 
Result so far: 29612.9094
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 14:
The number 861 fits into 6600 7 times, leaving a remainder of 573.
Write down 7 as next digit of the result. 
Result so far: 29612.909407
Deduct 6027 from 6600 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Moving on to step 15:
When dividing 5730 by 861, we get 6 with a remainder of 564.
The number 6 becomes the next digit in our result. 
Result so far: 29612.9094076
If we subtract 5166 from 5730, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 16:
861 can be fit into 5640 6 times, resulting in a remainder of 474.
Record the quotient 6 as the next digit in the result. 
Result so far: 29612.90940766
If we take 5166 away from 5640, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

The final outcome is 29612.90940766, with a leftover of 4.74e-07.
