842701 ÷ 45 
The aim is to understand the frequency of 45 in 842701.

Moving on to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 45

Moving on to step 2:
84 divided by 45 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 84 and we're left with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 45

Let's proceed to step 3:
If we divide 392 by 45, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 360 away from 392, we end up with 32.
Fetch the next digit (7) from the dividend, attach it to 32 and continue: 327 / 45

Advancing to step 4:
If we divide 327 by 45, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtract 315 from 327 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 45

On to step 5:
The number 45 fits into 120 2 times, leaving a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 1872.0
Subtract 90 from 120 to get 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 45

Advancing to step 6:
45 can be fit into 301 6 times, resulting in a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 18726.0
Subtract 270 from 301 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
45 goes into 310 6 times with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 18726.6
Deduct 270 from 310 and we're left 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.

Going ahead to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 18726.68
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.

Let's proceed to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 18726.688
Subtract 360 from 400 to 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.

The final outcome is 18726.688, with a leftover of 0.004.
