We divide 720645 by 32
The aim is to understand the frequency of 32 in 720645.

Let's proceed to step 1:
32 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 32

On to step 2:
72 divided by 32 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 64 from 72 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 32

Let's proceed to step 3:
32 can be fit into 80 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 64 away from 80, we end up with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 32

On to step 4:
32 goes into 166 5 times with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 225.0
If we take 160 away from 166, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 32

On to step 5:
The number 32 fits into 64 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2252.0
The remainder is 0 after subtracting 64 from 64.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 32

Moving on to step 6:
32 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 22520.0
Subtracting 0 from 5 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 32 fits into 50 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 22520.1
If we subtract 32 from 50, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
The number 32 fits into 180 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 22520.15
The remainder is 20 after subtracting 160 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
32 can be fit into 200 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 22520.156
If we take 192 away from 200, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 32 fits into 80 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 22520.1562
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 32 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 22520.15625
Deduct 160 from 160 and we're left 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 12:
32 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22520.15625
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.

On to step 13:
If we divide 0 by 32, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22520.15625
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.

The final outcome is 22520.15625, with a leftover of 0.0.
