91155152 ÷ 60 
The aim is to understand the frequency of 60 in 91155152.

Advancing to step 1:
When dividing 9 by 60, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 60

On to step 2:
60 can be fit into 91 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 60 from 91 leaves us with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 60

Going ahead to step 3:
60 goes into 311 5 times with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 300 from 311, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 60

Going ahead to step 4:
115 divided by 60 is 1 with a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Deduct 60 from 115 and we're left with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 60

Advancing to step 5:
60 can be fit into 555 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 1519.0
If we take 540 away from 555, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 60

Advancing to step 6:
The number 60 fits into 151 2 times, leaving a remainder of 31.
The next digit of our result is 2. 
Result so far: 15192.0
The remainder is 31 after subtracting 120 from 151.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 60

Let's proceed to step 7:
When dividing 315 by 60, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 151925.0
If we take 300 away from 315, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 60

Step 8:
The number 60 fits into 152 2 times, leaving a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1519252.0
Subtracting 120 from 152 leaves us with 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 9:
If we divide 320 by 60, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1519252.5
If we subtract 300 from 320, 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.

On to step 10:
If we divide 200 by 60, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 1519252.53
Subtracting 180 from 200 leaves us 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.

On to step 11:
When dividing 200 by 60, we get 3 with a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 1519252.533
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 1519252.533 and a remainder of 0.002.
