Let's divide 463501 by 45
The aim is to understand the frequency of 45 in 463501.

Step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 45

On to step 2:
45 can be fit into 46 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 45 from 46 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 45

Advancing to step 3:
The number 45 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 45

Step 4:
45 goes into 135 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we subtract 135 from 135, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 45

Step 5:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1030.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 45

Step 6:
1 divided by 45 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10300.0
If we take 0 away from 1, we end up with 1.
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: 10300.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 10300.02
If we take 90 away from 100, we end up 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.

Going ahead to step 9:
When dividing 100 by 45, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 10300.022
Deduct 90 from 100 and we're left 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.

After the division, we end up with 10300.022 and a remainder of 0.001.
