Let's divide 25210795 by 861
Our goal is to divide 25210795 by 861.

Going ahead to step 1:
2 divided by 861 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 861

Advancing to step 2:
25 divided by 861 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 861

On to step 3:
The number 861 fits into 252 0 times, leaving a remainder of 252.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 252 leaves us with 252.
Bring next digit (1) of the dividend behind the 252 and repeat the process: 2521 / 861

On to step 4:
If we divide 2521 by 861, we get 2 and a remainder of 799.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1722 from 2521 and we're left with 799.
Bring next digit (0) of the dividend behind the 799 and repeat the process: 7990 / 861

Going ahead to step 5:
861 goes into 7990 9 times with a remainder of 241.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 241 after subtracting 7749 from 7990.
Append the next digit (7) from the dividend to 241 and continue with: 2417 / 861

Step 6:
When dividing 2417 by 861, we get 2 with a remainder of 695.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
If we subtract 1722 from 2417, we get 695.
Append the next digit (9) from the dividend to 695 and continue with: 6959 / 861

On to step 7:
6959 divided by 861 is 8 with a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 2928.0
The remainder is 71 after subtracting 6888 from 6959.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 861

On to step 8:
861 goes into 715 0 times with a remainder of 715.
The number 0 becomes the next digit in our result. 
Result so far: 29280.0
Subtract 0 from 715 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Advancing to step 9:
The number 861 fits into 7150 8 times, leaving a remainder of 262.
The number 8 becomes the next digit in our result. 
Result so far: 29280.8
The remainder is 262 after subtracting 6888 from 7150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
861 can be fit into 2620 3 times, resulting in a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 29280.83
If we subtract 2583 from 2620, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
The number 861 fits into 370 0 times, leaving a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 29280.83
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 12:
861 goes into 3700 4 times with a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 29280.8304
Subtracting 3444 from 3700 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 13:
861 goes into 2560 2 times with a remainder of 838.
Write down 2 as next digit of the result. 
Result so far: 29280.83042
If we take 1722 away from 2560, we end up with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Moving on to step 14:
The number 861 fits into 8380 9 times, leaving a remainder of 631.
Write down 9 as next digit of the result. 
Result so far: 29280.830429
If we subtract 7749 from 8380, we get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Advancing to step 15:
The number 861 fits into 6310 7 times, leaving a remainder of 283.
The next digit of our result is 7. 
Result so far: 29280.8304297
Subtract 6027 from 6310 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 16:
861 goes into 2830 3 times with a remainder of 247.
The next digit of our result is 3. 
Result so far: 29280.83042973
Subtracting 2583 from 2830 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

The final result is 29280.83042973 with a remainder of 2.47e-07.
