Let's divide 87428571 by 769
The aim is to understand the frequency of 769 in 87428571.

Let's proceed to step 1:
If we divide 8 by 769, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 769

On to step 2:
If we divide 87 by 769, we get 0 and a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Take the next digit (4) from the dividend and append it to 87, then repeat: 874 / 769

Step 3:
When dividing 874 by 769, we get 1 with a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 769 from 874 and we're left with 105.
Include the next digit (2) from the dividend after 105, then repeat: 1052 / 769

On to step 4:
769 goes into 1052 1 times with a remainder of 283.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 283 after subtracting 769 from 1052.
Take the next digit (8) from the dividend and append it to 283, then repeat: 2838 / 769

Moving on to step 5:
769 goes into 2838 3 times with a remainder of 531.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtracting 2307 from 2838 leaves us with 531.
Grab the next digit (5) from the dividend, add it to 531, then carry on: 5315 / 769

Going ahead to step 6:
5315 divided by 769 is 6 with a remainder of 701.
Write down 6 as next digit of the result. 
Result so far: 1136.0
If we take 4614 away from 5315, we end up with 701.
Grab the next digit (7) from the dividend, add it to 701, then carry on: 7017 / 769

Moving on to step 7:
The number 769 fits into 7017 9 times, leaving a remainder of 96.
The next digit of our result is 9. 
Result so far: 11369.0
Subtract 6921 from 7017 to get 96.
Take the next digit (1) from the dividend and append it to 96, then repeat: 961 / 769

On to step 8:
769 goes into 961 1 times with a remainder of 192.
Write down 1 as next digit of the result. 
Result so far: 113691.0
If we subtract 769 from 961, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 9:
When dividing 1920 by 769, we get 2 with a remainder of 382.
Record the quotient 2 as the next digit in the result. 
Result so far: 113691.2
Subtracting 1538 from 1920 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 10:
769 goes into 3820 4 times with a remainder of 744.
Record the quotient 4 as the next digit in the result. 
Result so far: 113691.24
The remainder is 744 after subtracting 3076 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 11:
When dividing 7440 by 769, we get 9 with a remainder of 519.
Record the quotient 9 as the next digit in the result. 
Result so far: 113691.249
If we subtract 6921 from 7440, we get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 12:
769 can be fit into 5190 6 times, resulting in a remainder of 576.
The next digit of our result is 6. 
Result so far: 113691.2496
If we subtract 4614 from 5190, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 13:
5760 divided by 769 is 7 with a remainder of 377.
The next digit of our result is 7. 
Result so far: 113691.24967
The remainder is 377 after subtracting 5383 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 14:
If we divide 3770 by 769, we get 4 and a remainder of 694.
The next digit of our result is 4. 
Result so far: 113691.249674
Deduct 3076 from 3770 and we're left with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Going ahead to step 15:
769 goes into 6940 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 113691.2496749
If we take 6921 away from 6940, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 16:
If we divide 190 by 769, we get 0 and a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 113691.2496749
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

In conclusion, the division gives 113691.2496749 with a balance of 1.9e-07.
