83691 divided by 45 
The aim is to understand the frequency of 45 in 83691.

Moving on to step 1:
45 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 45

On to step 2:
45 can be fit into 83 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 83, we get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 45

Step 3:
45 goes into 386 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 360 from 386 leaves us with 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 45

Going ahead to step 4:
269 divided by 45 is 5 with a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Subtract 225 from 269 to get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 45

Moving on to step 5:
441 divided by 45 is 9 with a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 1859.0
Subtract 405 from 441 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 6:
The number 45 fits into 360 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1859.8
Subtracting 360 from 360 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 45 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1859.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1859.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1859.8, with a leftover of 0.0.
