76771684 ÷ 89 
The aim is to understand the frequency of 89 in 76771684.

Step 1:
89 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 89

Going ahead to step 2:
If we divide 76 by 89, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 89

Let's proceed to step 3:
89 can be fit into 767 8 times, resulting in a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 712 from 767 leaves us with 55.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 89

On to step 4:
When dividing 557 by 89, we get 6 with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 23 after subtracting 534 from 557.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 89

Moving on to step 5:
The number 89 fits into 231 2 times, leaving a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 862.0
Deduct 178 from 231 and we're left with 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 89

Going ahead to step 6:
If we divide 536 by 89, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 8626.0
Deduct 534 from 536 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 89

On to step 7:
89 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 86260.0
Subtract 0 from 28 to get 28.
Grab the next digit (4) from the dividend, add it to 28, then carry on: 284 / 89

Going ahead to step 8:
89 goes into 284 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 862603.0
The remainder is 17 after subtracting 267 from 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
If we divide 170 by 89, we get 1 and a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 862603.1
The remainder is 81 after subtracting 89 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
810 divided by 89 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 862603.19
The remainder is 9 after subtracting 801 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 89, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 862603.191
Subtract 89 from 90 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
When dividing 10 by 89, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 862603.191
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 89 fits into 100 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 862603.19101
If we take 89 away from 100, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
110 divided by 89 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 862603.191011
The remainder is 21 after subtracting 89 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 862603.191011, with a leftover of 2.1e-06.
