89046478 ÷ 86 
The aim is to understand the frequency of 86 in 89046478.

Step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 86

Going ahead to step 2:
If we divide 89 by 86, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 86 from 89 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

Let's proceed to step 3:
86 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 86

Step 4:
86 goes into 304 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Subtract 258 from 304 to get 46.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 86

On to step 5:
The number 86 fits into 466 5 times, leaving a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 1035.0
If we take 430 away from 466, we end up with 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 86

Advancing to step 6:
86 goes into 364 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 10354.0
Subtracting 344 from 364 leaves us with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 86

Let's proceed to step 7:
86 can be fit into 207 2 times, resulting in a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 103542.0
If we subtract 172 from 207, we get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 86

Step 8:
The number 86 fits into 358 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 1035424.0
If we take 344 away from 358, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1035424.1
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
When dividing 540 by 86, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1035424.16
Subtract 516 from 540 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
86 goes into 240 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 1035424.162
If we take 172 away from 240, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
680 divided by 86 is 7 with a remainder of 78.
The next digit of our result is 7. 
Result so far: 1035424.1627
Subtract 602 from 680 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 13:
86 goes into 780 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1035424.16279
Subtracting 774 from 780 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 86 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1035424.16279
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
86 goes into 600 6 times with a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 1035424.1627906
If we take 516 away from 600, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 16:
The number 86 fits into 840 9 times, leaving a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 1035424.16279069
Subtracting 774 from 840 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 1035424.16279069, and the remainder is 6.6e-08.
