We're dividing 55271850 by 431 
The aim is to understand the frequency of 431 in 55271850.

On to step 1:
When dividing 5 by 431, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 431

Going ahead to step 2:
431 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 431

On to step 3:
552 divided by 431 is 1 with a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 431 away from 552, we end up with 121.
Append the next digit (7) from the dividend to 121 and continue with: 1217 / 431

On to step 4:
If we divide 1217 by 431, we get 2 and a remainder of 355.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 862 from 1217 to get 355.
Grab the next digit (1) from the dividend, add it to 355, then carry on: 3551 / 431

Advancing to step 5:
If we divide 3551 by 431, we get 8 and a remainder of 103.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 3448 from 3551, we get 103.
Bring next digit (8) of the dividend behind the 103 and repeat the process: 1038 / 431

Moving on to step 6:
431 can be fit into 1038 2 times, resulting in a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 1282.0
If we take 862 away from 1038, we end up with 176.
Append the next digit (5) from the dividend to 176 and continue with: 1765 / 431

Let's proceed to step 7:
If we divide 1765 by 431, we get 4 and a remainder of 41.
The next digit of our result is 4. 
Result so far: 12824.0
The remainder is 41 after subtracting 1724 from 1765.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 431

Moving on to step 8:
If we divide 410 by 431, we get 0 and a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 128240.0
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 9:
431 goes into 4100 9 times with a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 128240.9
Subtract 3879 from 4100 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 10:
2210 divided by 431 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 128240.95
If we subtract 2155 from 2210, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 11:
550 divided by 431 is 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 128240.951
If we subtract 431 from 550, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 12:
1190 divided by 431 is 2 with a remainder of 328.
The next digit of our result is 2. 
Result so far: 128240.9512
Deduct 862 from 1190 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 13:
3280 divided by 431 is 7 with a remainder of 263.
Record the quotient 7 as the next digit in the result. 
Result so far: 128240.95127
The remainder is 263 after subtracting 3017 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 14:
2630 divided by 431 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 128240.951276
If we take 2586 away from 2630, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 15:
431 can be fit into 440 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 128240.9512761
If we subtract 431 from 440, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 16:
If we divide 90 by 431, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 128240.9512761
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 128240.9512761 and a remainder of 9e-08.
