8457303 divided by 233 
The aim is to understand the frequency of 233 in 8457303.

Going ahead to step 1:
When dividing 8 by 233, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 233

On to step 2:
233 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 233

Let's proceed to step 3:
When dividing 845 by 233, we get 3 with a remainder of 146.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 699 from 845 and we're left with 146.
Fetch the next digit (7) from the dividend, attach it to 146 and continue: 1467 / 233

Let's proceed to step 4:
When dividing 1467 by 233, we get 6 with a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 69 after subtracting 1398 from 1467.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 233

Advancing to step 5:
233 can be fit into 693 2 times, resulting in a remainder of 227.
Put 2 as the next digit of the answer. 
Result so far: 362.0
If we subtract 466 from 693, we get 227.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 233

Moving on to step 6:
233 can be fit into 2270 9 times, resulting in a remainder of 173.
The next digit of our result is 9. 
Result so far: 3629.0
If we subtract 2097 from 2270, we get 173.
Include the next digit (3) from the dividend after 173, then repeat: 1733 / 233

On to step 7:
When dividing 1733 by 233, we get 7 with a remainder of 102.
Put 7 as the next digit of the answer. 
Result so far: 36297.0
If we subtract 1631 from 1733, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 8:
233 can be fit into 1020 4 times, resulting in a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 36297.4
If we take 932 away from 1020, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
The number 233 fits into 880 3 times, leaving a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 36297.43
If we subtract 699 from 880, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 10:
The number 233 fits into 1810 7 times, leaving a remainder of 179.
Write down 7 as next digit of the result. 
Result so far: 36297.437
Deduct 1631 from 1810 and we're left with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 11:
When dividing 1790 by 233, we get 7 with a remainder of 159.
Put 7 as the next digit of the answer. 
Result so far: 36297.4377
Deduct 1631 from 1790 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The quotient of the division is 36297.4377, and the remainder is 0.00159.
