We look at the division of 85990338 by 25 
We want to divide 85990338 by 25.

Advancing to step 1:
The number 25 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 25

Advancing to step 2:
When dividing 85 by 25, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 10 after subtracting 75 from 85.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 25

Moving on to step 3:
The number 25 fits into 109 4 times, leaving a remainder of 9.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 100 from 109 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 25

Step 4:
The number 25 fits into 99 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 343.0
Subtract 75 from 99 to get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 25

Advancing to step 5:
The number 25 fits into 240 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 3439.0
The remainder is 15 after subtracting 225 from 240.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 25

Advancing to step 6:
153 divided by 25 is 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 34396.0
Subtract 150 from 153 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 25

Advancing to step 7:
25 can be fit into 33 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 343961.0
Deduct 25 from 33 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 25

On to step 8:
25 can be fit into 88 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3439613.0
If we subtract 75 from 88, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
25 goes into 130 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3439613.5
If we subtract 125 from 130, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
25 goes into 50 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 3439613.52
Subtract 50 from 50 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3439613.52
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3439613.52
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.

The final outcome is 3439613.52, with a leftover of 0.0.
