We look at the division of 84128079 by 425 
We want to figure out the number of times 84128079 can be divided by 425.

Step 1:
If we divide 8 by 425, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 425

Advancing to step 2:
If we divide 84 by 425, we get 0 and a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 425

Step 3:
425 goes into 841 1 times with a remainder of 416.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 425 from 841 leaves us with 416.
Grab the next digit (2) from the dividend, add it to 416, then carry on: 4162 / 425

Moving on to step 4:
425 can be fit into 4162 9 times, resulting in a remainder of 337.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 3825 from 4162, we get 337.
Include the next digit (8) from the dividend after 337, then repeat: 3378 / 425

Moving on to step 5:
When dividing 3378 by 425, we get 7 with a remainder of 403.
Put 7 as the next digit of the answer. 
Result so far: 197.0
Deduct 2975 from 3378 and we're left with 403.
Include the next digit (0) from the dividend after 403, then repeat: 4030 / 425

Advancing to step 6:
When dividing 4030 by 425, we get 9 with a remainder of 205.
Put 9 as the next digit of the answer. 
Result so far: 1979.0
Subtract 3825 from 4030 to get 205.
Include the next digit (7) from the dividend after 205, then repeat: 2057 / 425

Advancing to step 7:
425 goes into 2057 4 times with a remainder of 357.
Record the quotient 4 as the next digit in the result. 
Result so far: 19794.0
Subtracting 1700 from 2057 leaves us with 357.
Bring next digit (9) of the dividend behind the 357 and repeat the process: 3579 / 425

Moving on to step 8:
The number 425 fits into 3579 8 times, leaving a remainder of 179.
Use 8 as the next digit of our solution. 
Result so far: 197948.0
Subtracting 3400 from 3579 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 9:
When dividing 1790 by 425, we get 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 197948.4
Subtract 1700 from 1790 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
425 goes into 900 2 times with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 197948.42
If we subtract 850 from 900, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
425 can be fit into 500 1 times, resulting in a remainder of 75.
Use 1 as the next digit of our solution. 
Result so far: 197948.421
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
425 goes into 750 1 times with a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 197948.4211
Subtract 425 from 750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

In conclusion, the division gives 197948.4211 with a balance of 0.00325.
