We look at the division of 54857745 by 431 
The aim is to understand the frequency of 431 in 54857745.

Step 1:
If we divide 5 by 431, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 431

Going ahead to step 2:
431 can be fit into 54 0 times, resulting in a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 431

Advancing to step 3:
548 divided by 431 is 1 with a remainder of 117.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 431 from 548 leaves us with 117.
Fetch the next digit (5) from the dividend, attach it to 117 and continue: 1175 / 431

Going ahead to step 4:
431 can be fit into 1175 2 times, resulting in a remainder of 313.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 313 after subtracting 862 from 1175.
Grab the next digit (7) from the dividend, add it to 313, then carry on: 3137 / 431

Let's proceed to step 5:
If we divide 3137 by 431, we get 7 and a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 127.0
Deduct 3017 from 3137 and we're left with 120.
Include the next digit (7) from the dividend after 120, then repeat: 1207 / 431

Advancing to step 6:
431 goes into 1207 2 times with a remainder of 345.
Record the quotient 2 as the next digit in the result. 
Result so far: 1272.0
The remainder is 345 after subtracting 862 from 1207.
Append the next digit (4) from the dividend to 345 and continue with: 3454 / 431

Going ahead to step 7:
The number 431 fits into 3454 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 12728.0
If we subtract 3448 from 3454, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 431

Let's proceed to step 8:
The number 431 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 127280.0
Subtracting 0 from 65 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
When dividing 650 by 431, we get 1 with a remainder of 219.
Put 1 as the next digit of the answer. 
Result so far: 127280.1
The remainder is 219 after subtracting 431 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 10:
When dividing 2190 by 431, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 127280.15
If we take 2155 away from 2190, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
350 divided by 431 is 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 127280.15
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 12:
431 can be fit into 3500 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 127280.1508
If we take 3448 away from 3500, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
520 divided by 431 is 1 with a remainder of 89.
Write down 1 as next digit of the result. 
Result so far: 127280.15081
Deduct 431 from 520 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 14:
If we divide 890 by 431, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 127280.150812
Deduct 862 from 890 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
The number 431 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 127280.150812
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 16:
If we divide 2800 by 431, we get 6 and a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 127280.15081206
The remainder is 214 after subtracting 2586 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Our division results in 127280.15081206 with a remaining 2.14e-07.
