We look at the division of 77520 by 58 
We want to figure out the number of times 77520 can be divided by 58.

Going ahead to step 1:
58 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 58

Step 2:
When dividing 77 by 58, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 58 from 77 and we're left with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 58

Going ahead to step 3:
58 goes into 195 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 21 after subtracting 174 from 195.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 58

On to step 4:
58 goes into 212 3 times with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 133.0
The remainder is 38 after subtracting 174 from 212.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 58

On to step 5:
380 divided by 58 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1336.0
If we subtract 348 from 380, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 6:
320 divided by 58 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1336.5
If we take 290 away from 320, 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.

Step 7:
When dividing 300 by 58, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 1336.55
The remainder is 10 after subtracting 290 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 1336.55 with a remainder of 0.01.
