663583 ÷ 60 
The aim is to understand the frequency of 60 in 663583.

Going ahead to step 1:
If we divide 6 by 60, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 60

On to step 2:
If we divide 66 by 60, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 60 from 66 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 60

Advancing to step 3:
60 goes into 63 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 60 from 63, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 60

Let's proceed to step 4:
The number 60 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtract 0 from 35 to get 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 60

Advancing to step 5:
The number 60 fits into 358 5 times, leaving a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 1105.0
Subtracting 300 from 358 leaves us with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 60

Step 6:
60 can be fit into 583 9 times, resulting in a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 11059.0
Subtract 540 from 583 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
60 can be fit into 430 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 11059.7
If we take 420 away from 430, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 60 is 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 11059.71
If we subtract 60 from 100, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 60 fits into 400 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 11059.716
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 60, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 11059.7166
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.

After the division, we end up with 11059.7166 and a remainder of 0.0004.
