19334987 ÷ 851 
The aim is to understand the frequency of 851 in 19334987.

Step 1:
851 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 851

Going ahead to step 2:
19 divided by 851 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 851

Let's proceed to step 3:
If we divide 193 by 851, we get 0 and a remainder of 193.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 193, we end up with 193.
Bring next digit (3) of the dividend behind the 193 and repeat the process: 1933 / 851

Moving on to step 4:
When dividing 1933 by 851, we get 2 with a remainder of 231.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1702 from 1933 and we're left with 231.
Grab the next digit (4) from the dividend, add it to 231, then carry on: 2314 / 851

Let's proceed to step 5:
2314 divided by 851 is 2 with a remainder of 612.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 1702 from 2314, we get 612.
Grab the next digit (9) from the dividend, add it to 612, then carry on: 6129 / 851

Let's proceed to step 6:
When dividing 6129 by 851, we get 7 with a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
If we take 5957 away from 6129, we end up with 172.
Take the next digit (8) from the dividend and append it to 172, then repeat: 1728 / 851

Moving on to step 7:
851 can be fit into 1728 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2272.0
Subtracting 1702 from 1728 leaves us with 26.
Append the next digit (7) from the dividend to 26 and continue with: 267 / 851

On to step 8:
When dividing 267 by 851, we get 0 with a remainder of 267.
Record the quotient 0 as the next digit in the result. 
Result so far: 22720.0
If we subtract 0 from 267, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 9:
If we divide 2670 by 851, we get 3 and a remainder of 117.
The number 3 becomes the next digit in our result. 
Result so far: 22720.3
If we subtract 2553 from 2670, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 10:
If we divide 1170 by 851, we get 1 and a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 22720.31
The remainder is 319 after subtracting 851 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 11:
851 goes into 3190 3 times with a remainder of 637.
Put 3 as the next digit of the answer. 
Result so far: 22720.313
If we take 2553 away from 3190, we end up with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

On to step 12:
851 can be fit into 6370 7 times, resulting in a remainder of 413.
Record the quotient 7 as the next digit in the result. 
Result so far: 22720.3137
The remainder is 413 after subtracting 5957 from 6370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

On to step 13:
If we divide 4130 by 851, we get 4 and a remainder of 726.
The number 4 becomes the next digit in our result. 
Result so far: 22720.31374
If we subtract 3404 from 4130, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Going ahead to step 14:
The number 851 fits into 7260 8 times, leaving a remainder of 452.
The next digit of our result is 8. 
Result so far: 22720.313748
The remainder is 452 after subtracting 6808 from 7260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 15:
If we divide 4520 by 851, we get 5 and a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 22720.3137485
If we take 4255 away from 4520, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 16:
2650 divided by 851 is 3 with a remainder of 97.
Write down 3 as next digit of the result. 
Result so far: 22720.31374853
Deduct 2553 from 2650 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

After the division, we end up with 22720.31374853 and a remainder of 9.7e-08.
