We look at the division of 391200 by 61 
Let's see how many times 61 fits into 391200.

On to step 1:
3 divided by 61 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 61

Going ahead to step 2:
The number 61 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 61

Step 3:
391 divided by 61 is 6 with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 366 away from 391, we end up with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 61

On to step 4:
252 divided by 61 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 244 from 252 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 61

Moving on to step 5:
The number 61 fits into 80 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 641.0
Subtracting 61 from 80 leaves us with 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 61

Step 6:
The number 61 fits into 190 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 6413.0
Subtracting 183 from 190 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.

Step 7:
When dividing 70 by 61, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 6413.1
The remainder is 9 after subtracting 61 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
90 divided by 61 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 6413.11
If we subtract 61 from 90, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 6413.11 with a remainder of 0.029.
