We're dividing 57403373 by 231 
The aim is to understand the frequency of 231 in 57403373.

Advancing to step 1:
5 divided by 231 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 231

Advancing to step 2:
231 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 231

Let's proceed to step 3:
When dividing 574 by 231, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 462 away from 574, we end up with 112.
Include the next digit (0) from the dividend after 112, then repeat: 1120 / 231

Let's proceed to step 4:
When dividing 1120 by 231, we get 4 with a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 924 from 1120 and we're left with 196.
Append the next digit (3) from the dividend to 196 and continue with: 1963 / 231

On to step 5:
231 goes into 1963 8 times with a remainder of 115.
Use 8 as the next digit of our solution. 
Result so far: 248.0
If we take 1848 away from 1963, we end up with 115.
Fetch the next digit (3) from the dividend, attach it to 115 and continue: 1153 / 231

Going ahead to step 6:
The number 231 fits into 1153 4 times, leaving a remainder of 229.
Use 4 as the next digit of our solution. 
Result so far: 2484.0
Deduct 924 from 1153 and we're left with 229.
Fetch the next digit (7) from the dividend, attach it to 229 and continue: 2297 / 231

Moving on to step 7:
If we divide 2297 by 231, we get 9 and a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 24849.0
If we take 2079 away from 2297, we end up with 218.
Bring next digit (3) of the dividend behind the 218 and repeat the process: 2183 / 231

Step 8:
231 can be fit into 2183 9 times, resulting in a remainder of 104.
The next digit of our result is 9. 
Result so far: 248499.0
Subtracting 2079 from 2183 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
231 goes into 1040 4 times with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 248499.4
If we subtract 924 from 1040, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
231 goes into 1160 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 248499.45
Subtract 1155 from 1160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
The number 231 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 248499.45
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
When dividing 500 by 231, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 248499.4502
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
When dividing 380 by 231, we get 1 with a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 248499.45021
The remainder is 149 after subtracting 231 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 14:
When dividing 1490 by 231, we get 6 with a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 248499.450216
If we take 1386 away from 1490, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 15:
The number 231 fits into 1040 4 times, leaving a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 248499.4502164
The remainder is 116 after subtracting 924 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 16:
1160 divided by 231 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 248499.45021645
Deduct 1155 from 1160 and we're left 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.

After the division, we end up with 248499.45021645 and a remainder of 5e-09.
