78599403 divided by 125 
We're looking to find how many times 125 goes into 78599403.

Let's proceed to step 1:
When dividing 7 by 125, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 125

Going ahead to step 2:
78 divided by 125 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 125

On to step 3:
The number 125 fits into 785 6 times, leaving a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 35 after subtracting 750 from 785.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 125

Advancing to step 4:
When dividing 359 by 125, we get 2 with a remainder of 109.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 109 after subtracting 250 from 359.
Take the next digit (9) from the dividend and append it to 109, then repeat: 1099 / 125

Advancing to step 5:
When dividing 1099 by 125, we get 8 with a remainder of 99.
The next digit of our result is 8. 
Result so far: 628.0
If we take 1000 away from 1099, we end up with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 125

Advancing to step 6:
125 goes into 994 7 times with a remainder of 119.
Use 7 as the next digit of our solution. 
Result so far: 6287.0
Subtracting 875 from 994 leaves us with 119.
Fetch the next digit (0) from the dividend, attach it to 119 and continue: 1190 / 125

Advancing to step 7:
If we divide 1190 by 125, we get 9 and a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 62879.0
If we subtract 1125 from 1190, we get 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 125

Going ahead to step 8:
If we divide 653 by 125, we get 5 and a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 628795.0
Deduct 625 from 653 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
280 divided by 125 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 628795.2
If we take 250 away from 280, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 125, we get 2 and a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 628795.22
If we take 250 away from 300, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 628795.22 with a remainder of 0.05.
