We divide 86438824 by 25
Our goal is to divide 86438824 by 25.

Step 1:
8 divided by 25 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 25

Step 2:
When dividing 86 by 25, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 75 from 86 to get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 25

Going ahead to step 3:
25 goes into 114 4 times with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 100 from 114, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 25

Going ahead to step 4:
25 goes into 143 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 345.0
If we take 125 away from 143, we end up with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 25

On to step 5:
25 can be fit into 188 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 3457.0
If we subtract 175 from 188, we get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 25

Going ahead to step 6:
138 divided by 25 is 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 34575.0
The remainder is 13 after subtracting 125 from 138.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 25

Moving on to step 7:
132 divided by 25 is 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 345755.0
Subtract 125 from 132 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 25

Going ahead to step 8:
25 goes into 74 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3457552.0
The remainder is 24 after subtracting 50 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
25 goes into 240 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 3457552.9
If we take 225 away from 240, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
If we divide 150 by 25, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 3457552.96
If we take 150 away from 150, we end up 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.

Step 11:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3457552.96
If we take 0 away from 0, we end up 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.

Step 12:
If we divide 0 by 25, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3457552.96
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 3457552.96 and a remainder of 0.0.
