We look at the division of 54604111 by 851 
The aim is to understand the frequency of 851 in 54604111.

On to step 1:
851 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 851

On to step 2:
If we divide 54 by 851, we get 0 and a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 851

Step 3:
546 divided by 851 is 0 with a remainder of 546.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 546 to get 546.
Bring next digit (0) of the dividend behind the 546 and repeat the process: 5460 / 851

Advancing to step 4:
851 can be fit into 5460 6 times, resulting in a remainder of 354.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 5106 from 5460 leaves us with 354.
Append the next digit (4) from the dividend to 354 and continue with: 3544 / 851

Let's proceed to step 5:
When dividing 3544 by 851, we get 4 with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 3404 from 3544 to get 140.
Take the next digit (1) from the dividend and append it to 140, then repeat: 1401 / 851

Step 6:
If we divide 1401 by 851, we get 1 and a remainder of 550.
Write down 1 as next digit of the result. 
Result so far: 641.0
The remainder is 550 after subtracting 851 from 1401.
Append the next digit (1) from the dividend to 550 and continue with: 5501 / 851

Going ahead to step 7:
5501 divided by 851 is 6 with a remainder of 395.
Record the quotient 6 as the next digit in the result. 
Result so far: 6416.0
Subtracting 5106 from 5501 leaves us with 395.
Fetch the next digit (1) from the dividend, attach it to 395 and continue: 3951 / 851

Advancing to step 8:
If we divide 3951 by 851, we get 4 and a remainder of 547.
Use 4 as the next digit of our solution. 
Result so far: 64164.0
If we subtract 3404 from 3951, we get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Advancing to step 9:
The number 851 fits into 5470 6 times, leaving a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 64164.6
The remainder is 364 after subtracting 5106 from 5470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 10:
851 can be fit into 3640 4 times, resulting in a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 64164.64
Subtract 3404 from 3640 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 11:
The number 851 fits into 2360 2 times, leaving a remainder of 658.
The next digit of our result is 2. 
Result so far: 64164.642
Subtracting 1702 from 2360 leaves us with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 12:
6580 divided by 851 is 7 with a remainder of 623.
The number 7 becomes the next digit in our result. 
Result so far: 64164.6427
If we take 5957 away from 6580, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Going ahead to step 13:
When dividing 6230 by 851, we get 7 with a remainder of 273.
Use 7 as the next digit of our solution. 
Result so far: 64164.64277
The remainder is 273 after subtracting 5957 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

The final outcome is 64164.64277, with a leftover of 0.000273.
