We look at the division of 72041845 by 851 
The aim is to understand the frequency of 851 in 72041845.

Moving on to step 1:
The number 851 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 851

Step 2:
72 divided by 851 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 851

Step 3:
720 divided by 851 is 0 with a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 720 after subtracting 0 from 720.
Append the next digit (4) from the dividend to 720 and continue with: 7204 / 851

Step 4:
7204 divided by 851 is 8 with a remainder of 396.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 396 after subtracting 6808 from 7204.
Grab the next digit (1) from the dividend, add it to 396, then carry on: 3961 / 851

Advancing to step 5:
851 goes into 3961 4 times with a remainder of 557.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtracting 3404 from 3961 leaves us with 557.
Bring next digit (8) of the dividend behind the 557 and repeat the process: 5578 / 851

Going ahead to step 6:
When dividing 5578 by 851, we get 6 with a remainder of 472.
Write down 6 as next digit of the result. 
Result so far: 846.0
If we take 5106 away from 5578, we end up with 472.
Take the next digit (4) from the dividend and append it to 472, then repeat: 4724 / 851

Step 7:
The number 851 fits into 4724 5 times, leaving a remainder of 469.
The next digit of our result is 5. 
Result so far: 8465.0
Subtract 4255 from 4724 to get 469.
Fetch the next digit (5) from the dividend, attach it to 469 and continue: 4695 / 851

Moving on to step 8:
When dividing 4695 by 851, we get 5 with a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 84655.0
If we subtract 4255 from 4695, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 9:
851 can be fit into 4400 5 times, resulting in a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 84655.5
If we subtract 4255 from 4400, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 10:
If we divide 1450 by 851, we get 1 and a remainder of 599.
Write down 1 as next digit of the result. 
Result so far: 84655.51
The remainder is 599 after subtracting 851 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Moving on to step 11:
5990 divided by 851 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 84655.517
Deduct 5957 from 5990 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
851 can be fit into 330 0 times, resulting in a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 84655.517
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 13:
When dividing 3300 by 851, we get 3 with a remainder of 747.
The next digit of our result is 3. 
Result so far: 84655.51703
If we take 2553 away from 3300, we end up with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Advancing to step 14:
851 goes into 7470 8 times with a remainder of 662.
The next digit of our result is 8. 
Result so far: 84655.517038
Subtract 6808 from 7470 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

On to step 15:
When dividing 6620 by 851, we get 7 with a remainder of 663.
The next digit of our result is 7. 
Result so far: 84655.5170387
Deduct 5957 from 6620 and we're left with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Going ahead to step 16:
If we divide 6630 by 851, we get 7 and a remainder of 673.
The next digit of our result is 7. 
Result so far: 84655.51703877
Deduct 5957 from 6630 and we're left with 673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6730, and continue the process.

Our division results in 84655.51703877 with a remaining 6.73e-07.
