97570919 divided by 60 
The aim is to understand the frequency of 60 in 97570919.

On to step 1:
60 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 60

Moving on to step 2:
97 divided by 60 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 60 from 97 leaves us with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 60

Step 3:
The number 60 fits into 375 6 times, leaving a remainder of 15.
The next digit of our result is 6. 
Result so far: 16.0
If we take 360 away from 375, we end up with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 60

Step 4:
60 goes into 157 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 162.0
Deduct 120 from 157 and we're left with 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 60

Going ahead to step 5:
370 divided by 60 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1626.0
If we take 360 away from 370, we end up with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 60

Advancing to step 6:
If we divide 109 by 60, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 16261.0
If we take 60 away from 109, we end up with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 60

Step 7:
60 can be fit into 491 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 162618.0
Subtract 480 from 491 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 60

Advancing to step 8:
The number 60 fits into 119 1 times, leaving a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1626181.0
If we take 60 away from 119, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 9:
60 goes into 590 9 times with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 1626181.9
Deduct 540 from 590 and we're left 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.

Step 10:
60 can be fit into 500 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 1626181.98
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 11:
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: 1626181.983
If we take 180 away from 200, we end up 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.

Advancing to step 12:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 1626181.9833
If we subtract 180 from 200, 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.

The final outcome is 1626181.9833, with a leftover of 0.0002.
