We look at the division of 728638 by 60 
Our goal is to divide 728638 by 60.

Going ahead to step 1:
60 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 60

Advancing to step 2:
60 goes into 72 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 60 from 72 to get 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 60

On to step 3:
60 can be fit into 128 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 120 from 128 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 60

Step 4:
60 can be fit into 86 1 times, resulting in a remainder of 26.
The next digit of our result is 1. 
Result so far: 121.0
Subtract 60 from 86 to get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 60

Advancing to step 5:
If we divide 263 by 60, we get 4 and a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 1214.0
If we take 240 away from 263, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 60

Moving on to step 6:
If we divide 238 by 60, we get 3 and a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 12143.0
Subtracting 180 from 238 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
60 can be fit into 580 9 times, resulting in a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 12143.9
If we take 540 away from 580, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
The number 60 fits into 400 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 12143.96
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 60, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 12143.966
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 12143.966, with a leftover of 0.004.
