We're dividing 76462079 by 866 
The aim is to understand the frequency of 866 in 76462079.

On to step 1:
866 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 866

Let's proceed to step 2:
866 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 866

On to step 3:
866 can be fit into 764 0 times, resulting in a remainder of 764.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 764 after subtracting 0 from 764.
Grab the next digit (6) from the dividend, add it to 764, then carry on: 7646 / 866

Advancing to step 4:
If we divide 7646 by 866, we get 8 and a remainder of 718.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 718 after subtracting 6928 from 7646.
Include the next digit (2) from the dividend after 718, then repeat: 7182 / 866

Advancing to step 5:
When dividing 7182 by 866, we get 8 with a remainder of 254.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we subtract 6928 from 7182, we get 254.
Grab the next digit (0) from the dividend, add it to 254, then carry on: 2540 / 866

Moving on to step 6:
When dividing 2540 by 866, we get 2 with a remainder of 808.
Write down 2 as next digit of the result. 
Result so far: 882.0
The remainder is 808 after subtracting 1732 from 2540.
Fetch the next digit (7) from the dividend, attach it to 808 and continue: 8087 / 866

On to step 7:
The number 866 fits into 8087 9 times, leaving a remainder of 293.
Put 9 as the next digit of the answer. 
Result so far: 8829.0
If we subtract 7794 from 8087, we get 293.
Include the next digit (9) from the dividend after 293, then repeat: 2939 / 866

Advancing to step 8:
When dividing 2939 by 866, we get 3 with a remainder of 341.
The next digit of our result is 3. 
Result so far: 88293.0
Deduct 2598 from 2939 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 9:
The number 866 fits into 3410 3 times, leaving a remainder of 812.
Record the quotient 3 as the next digit in the result. 
Result so far: 88293.3
The remainder is 812 after subtracting 2598 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

On to step 10:
866 goes into 8120 9 times with a remainder of 326.
Write down 9 as next digit of the result. 
Result so far: 88293.39
Deduct 7794 from 8120 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 11:
866 goes into 3260 3 times with a remainder of 662.
Write down 3 as next digit of the result. 
Result so far: 88293.393
The remainder is 662 after subtracting 2598 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Advancing to step 12:
When dividing 6620 by 866, we get 7 with a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 88293.3937
Subtract 6062 from 6620 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 13:
If we divide 5580 by 866, we get 6 and a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 88293.39376
Subtracting 5196 from 5580 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 14:
3840 divided by 866 is 4 with a remainder of 376.
Write down 4 as next digit of the result. 
Result so far: 88293.393764
Subtract 3464 from 3840 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 15:
3760 divided by 866 is 4 with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 88293.3937644
Subtracting 3464 from 3760 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

After the division, we end up with 88293.3937644 and a remainder of 2.96e-06.
