883645 divided by 60 
The aim is to understand the frequency of 60 in 883645.

Going ahead to step 1:
If we divide 8 by 60, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 60

Going ahead to step 2:
60 can be fit into 88 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 60 from 88 to get 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 60

Advancing to step 3:
283 divided by 60 is 4 with a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 240 from 283 and we're left with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 60

Moving on to step 4:
60 can be fit into 436 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 147.0
If we subtract 420 from 436, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 60

Advancing to step 5:
When dividing 164 by 60, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 1472.0
Deduct 120 from 164 and we're left with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 60

Moving on to step 6:
60 can be fit into 445 7 times, resulting in a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 14727.0
If we take 420 away from 445, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
60 can be fit into 250 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 14727.4
Subtract 240 from 250 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 60 is 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 14727.41
The remainder is 40 after subtracting 60 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
400 divided by 60 is 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 14727.416
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.

Going ahead to step 10:
60 goes into 400 6 times with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 14727.4166
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.

The final outcome is 14727.4166, with a leftover of 0.0004.
