63607 ÷ 45 
The aim is to understand the frequency of 45 in 63607.

Step 1:
45 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 45

Let's proceed to step 2:
When dividing 63 by 45, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 63 leaves us with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 45

Step 3:
45 goes into 186 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 180 away from 186, we end up with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 45

Step 4:
If we divide 60 by 45, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Deduct 45 from 60 and we're left with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 45

On to step 5:
45 can be fit into 157 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 1413.0
Deduct 135 from 157 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 6:
If we divide 220 by 45, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 1413.4
If we subtract 180 from 220, 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.

Advancing to step 7:
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: 1413.48
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 8:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1413.488
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.

In conclusion, the division gives 1413.488 with a balance of 0.004.
