We divide 91145153 by 60
We want to figure out the number of times 91145153 can be divided by 60.

On to step 1:
60 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 60

Moving on to step 2:
60 goes into 91 1 times with a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 60 from 91 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 60

Going ahead to step 3:
311 divided by 60 is 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 300 from 311 and we're left with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 60

Going ahead to step 4:
The number 60 fits into 114 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 151.0
Subtracting 60 from 114 leaves us with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 60

On to step 5:
If we divide 545 by 60, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1519.0
Subtracting 540 from 545 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 60

Moving on to step 6:
When dividing 51 by 60, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 15190.0
If we take 0 away from 51, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 60

Let's proceed to step 7:
60 goes into 515 8 times with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 151908.0
Subtract 480 from 515 to get 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 60

Step 8:
60 goes into 353 5 times with a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 1519085.0
If we subtract 300 from 353, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
If we divide 530 by 60, we get 8 and a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 1519085.8
If we subtract 480 from 530, 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 10:
The number 60 fits into 500 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 1519085.88
Deduct 480 from 500 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.

Our division results in 1519085.88 with a remaining 0.02.
