We divide 45151232 by 623
The aim is to understand the frequency of 623 in 45151232.

On to step 1:
The number 623 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 623

Moving on to step 2:
When dividing 45 by 623, we get 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 623

Step 3:
If we divide 451 by 623, we get 0 and a remainder of 451.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 451 and we're left with 451.
Include the next digit (5) from the dividend after 451, then repeat: 4515 / 623

Going ahead to step 4:
If we divide 4515 by 623, we get 7 and a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 4361 away from 4515, we end up with 154.
Take the next digit (1) from the dividend and append it to 154, then repeat: 1541 / 623

Let's proceed to step 5:
The number 623 fits into 1541 2 times, leaving a remainder of 295.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 1246 from 1541, we get 295.
Append the next digit (2) from the dividend to 295 and continue with: 2952 / 623

Going ahead to step 6:
The number 623 fits into 2952 4 times, leaving a remainder of 460.
Record the quotient 4 as the next digit in the result. 
Result so far: 724.0
Subtract 2492 from 2952 to get 460.
Include the next digit (3) from the dividend after 460, then repeat: 4603 / 623

On to step 7:
The number 623 fits into 4603 7 times, leaving a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 7247.0
Subtract 4361 from 4603 to get 242.
Grab the next digit (2) from the dividend, add it to 242, then carry on: 2422 / 623

Moving on to step 8:
623 can be fit into 2422 3 times, resulting in a remainder of 553.
The next digit of our result is 3. 
Result so far: 72473.0
If we take 1869 away from 2422, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 9:
623 goes into 5530 8 times with a remainder of 546.
Use 8 as the next digit of our solution. 
Result so far: 72473.8
If we subtract 4984 from 5530, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Going ahead to step 10:
5460 divided by 623 is 8 with a remainder of 476.
Write down 8 as next digit of the result. 
Result so far: 72473.88
Deduct 4984 from 5460 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final outcome is 72473.88, with a leftover of 0.476.
