We're dividing 69762930 by 851 
The aim is to understand the frequency of 851 in 69762930.

On to step 1:
6 divided by 851 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 851

On to step 2:
69 divided by 851 is 0 with a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 851

Going ahead to step 3:
851 can be fit into 697 0 times, resulting in a remainder of 697.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 697 leaves us with 697.
Include the next digit (6) from the dividend after 697, then repeat: 6976 / 851

On to step 4:
851 goes into 6976 8 times with a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 168 after subtracting 6808 from 6976.
Include the next digit (2) from the dividend after 168, then repeat: 1682 / 851

Moving on to step 5:
851 goes into 1682 1 times with a remainder of 831.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we subtract 851 from 1682, we get 831.
Take the next digit (9) from the dividend and append it to 831, then repeat: 8319 / 851

Going ahead to step 6:
When dividing 8319 by 851, we get 9 with a remainder of 660.
Put 9 as the next digit of the answer. 
Result so far: 819.0
The remainder is 660 after subtracting 7659 from 8319.
Append the next digit (3) from the dividend to 660 and continue with: 6603 / 851

Let's proceed to step 7:
If we divide 6603 by 851, we get 7 and a remainder of 646.
Use 7 as the next digit of our solution. 
Result so far: 8197.0
Subtract 5957 from 6603 to get 646.
Fetch the next digit (0) from the dividend, attach it to 646 and continue: 6460 / 851

Moving on to step 8:
The number 851 fits into 6460 7 times, leaving a remainder of 503.
The number 7 becomes the next digit in our result. 
Result so far: 81977.0
The remainder is 503 after subtracting 5957 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 9:
If we divide 5030 by 851, we get 5 and a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 81977.5
Subtracting 4255 from 5030 leaves us with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Moving on to step 10:
851 can be fit into 7750 9 times, resulting in a remainder of 91.
The next digit of our result is 9. 
Result so far: 81977.59
The remainder is 91 after subtracting 7659 from 7750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 11:
When dividing 910 by 851, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 81977.591
Deduct 851 from 910 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
851 goes into 590 0 times with a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 81977.591
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 13:
The number 851 fits into 5900 6 times, leaving a remainder of 794.
The number 6 becomes the next digit in our result. 
Result so far: 81977.59106
The remainder is 794 after subtracting 5106 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

On to step 14:
When dividing 7940 by 851, we get 9 with a remainder of 281.
Put 9 as the next digit of the answer. 
Result so far: 81977.591069
If we subtract 7659 from 7940, we get 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Going ahead to step 15:
851 goes into 2810 3 times with a remainder of 257.
Use 3 as the next digit of our solution. 
Result so far: 81977.5910693
If we subtract 2553 from 2810, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Moving on to step 16:
The number 851 fits into 2570 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 81977.59106933
Deduct 2553 from 2570 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 81977.59106933, with a leftover of 1.7e-08.
