Let's divide 55138801 by 233
The aim is to understand the frequency of 233 in 55138801.

On to step 1:
When dividing 5 by 233, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 233

Moving on to step 2:
When dividing 55 by 233, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 233

On to step 3:
233 goes into 551 2 times with a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 466 from 551 to get 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 233

Going ahead to step 4:
233 goes into 853 3 times with a remainder of 154.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 699 from 853 leaves us with 154.
Append the next digit (8) from the dividend to 154 and continue with: 1548 / 233

On to step 5:
The number 233 fits into 1548 6 times, leaving a remainder of 150.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
If we subtract 1398 from 1548, we get 150.
Fetch the next digit (8) from the dividend, attach it to 150 and continue: 1508 / 233

Moving on to step 6:
When dividing 1508 by 233, we get 6 with a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 2366.0
If we take 1398 away from 1508, we end up with 110.
Grab the next digit (0) from the dividend, add it to 110, then carry on: 1100 / 233

Let's proceed to step 7:
When dividing 1100 by 233, we get 4 with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 23664.0
Deduct 932 from 1100 and we're left with 168.
Append the next digit (1) from the dividend to 168 and continue with: 1681 / 233

Moving on to step 8:
The number 233 fits into 1681 7 times, leaving a remainder of 50.
The next digit of our result is 7. 
Result so far: 236647.0
The remainder is 50 after subtracting 1631 from 1681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
If we divide 500 by 233, we get 2 and a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 236647.2
Deduct 466 from 500 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
233 goes into 340 1 times with a remainder of 107.
The next digit of our result is 1. 
Result so far: 236647.21
Deduct 233 from 340 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 11:
The number 233 fits into 1070 4 times, leaving a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 236647.214
If we take 932 away from 1070, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 12:
If we divide 1380 by 233, we get 5 and a remainder of 215.
The next digit of our result is 5. 
Result so far: 236647.2145
If we take 1165 away from 1380, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 13:
233 goes into 2150 9 times with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 236647.21459
Deduct 2097 from 2150 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 14:
When dividing 530 by 233, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 236647.214592
Subtracting 466 from 530 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
640 divided by 233 is 2 with a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 236647.2145922
The remainder is 174 after subtracting 466 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

After the division, we end up with 236647.2145922 and a remainder of 1.74e-06.
