We divide 86021782 by 25
We want to divide 86021782 by 25.

Advancing to step 1:
8 divided by 25 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 25

Advancing to step 2:
25 goes into 86 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 75 from 86 and we're left with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 25

Step 3:
110 divided by 25 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 10 after subtracting 100 from 110.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 25

Advancing to step 4:
When dividing 102 by 25, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 344.0
If we subtract 100 from 102, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 25

Step 5:
25 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 3440.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 25

On to step 6:
If we divide 217 by 25, we get 8 and a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 34408.0
If we subtract 200 from 217, we get 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 25

Advancing to step 7:
The number 25 fits into 178 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 344087.0
The remainder is 3 after subtracting 175 from 178.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 25

Step 8:
25 goes into 32 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 3440871.0
Subtracting 25 from 32 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
When dividing 70 by 25, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 3440871.2
Deduct 50 from 70 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 25 fits into 200 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 3440871.28
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3440871.28
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3440871.28
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3440871.28 with a remainder of 0.0.
