We're dividing 354286 by 45 
The aim is to understand the frequency of 45 in 354286.

On to step 1:
45 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 45

Step 2:
45 can be fit into 35 0 times, resulting in a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 45

Let's proceed to step 3:
The number 45 fits into 354 7 times, leaving a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 315 from 354 leaves us with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 45

Going ahead to step 4:
The number 45 fits into 392 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 360 from 392 and we're left with 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 45

Let's proceed to step 5:
45 can be fit into 328 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 787.0
Deduct 315 from 328 and we're left with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 45

Advancing to step 6:
If we divide 136 by 45, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 7873.0
The remainder is 1 after subtracting 135 from 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 45, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 7873.0
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 8:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 7873.02
Subtracting 90 from 100 leaves us 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.

Moving on to step 9:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 7873.022
Subtracting 90 from 100 leaves us 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.

In conclusion, the division gives 7873.022 with a balance of 0.001.
