We look at the division of 127991 by 60 
We want to figure out the number of times 127991 can be divided by 60.

On to step 1:
60 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 60

Advancing to step 2:
60 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 60

Going ahead to step 3:
127 divided by 60 is 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 7 after subtracting 120 from 127.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 60

On to step 4:
The number 60 fits into 79 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 60 from 79, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 60

Going ahead to step 5:
60 goes into 199 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 213.0
The remainder is 19 after subtracting 180 from 199.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 60

Moving on to step 6:
60 goes into 191 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 2133.0
If we subtract 180 from 191, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 60 fits into 110 1 times, leaving a remainder of 50.
The next digit of our result is 1. 
Result so far: 2133.1
If we take 60 away from 110, 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.

On to step 8:
500 divided by 60 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 2133.18
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
60 can be fit into 200 3 times, resulting in a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 2133.183
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 60, we get 3 and a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 2133.1833
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 2133.1833, with a leftover of 0.0002.
