85774086 ÷ 86 
The aim is to understand the frequency of 86 in 85774086.

Advancing to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 86

Advancing to step 2:
86 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Take the next digit (7) from the dividend and append it to 85, then repeat: 857 / 86

Going ahead to step 3:
86 can be fit into 857 9 times, resulting in a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 774 from 857, we get 83.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 86

Advancing to step 4:
86 goes into 837 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 63 after subtracting 774 from 837.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 86

Advancing to step 5:
86 goes into 634 7 times with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 997.0
Subtracting 602 from 634 leaves us with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 86

On to step 6:
86 can be fit into 320 3 times, resulting in a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 9973.0
Subtract 258 from 320 to get 62.
Include the next digit (8) from the dividend after 62, then repeat: 628 / 86

Moving on to step 7:
When dividing 628 by 86, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 99737.0
Subtract 602 from 628 to get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 86

Step 8:
When dividing 266 by 86, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 997373.0
Deduct 258 from 266 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
86 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 997373.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
800 divided by 86 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 997373.09
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 997373.093
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
20 divided by 86 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 997373.093
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 86 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 997373.09302
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
If we divide 280 by 86, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 997373.093023
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 15:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 997373.0930232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 16:
If we divide 480 by 86, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 997373.09302325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 997373.09302325 with a remaining 5e-08.
