We divide 691833 by 86
The aim is to understand the frequency of 86 in 691833.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 86

Let's proceed to step 2:
69 divided by 86 is 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 86

On to step 3:
When dividing 691 by 86, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 688 from 691 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 86

Going ahead to step 4:
If we divide 38 by 86, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 86

Advancing to step 5:
When dividing 383 by 86, we get 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 804.0
The remainder is 39 after subtracting 344 from 383.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 86

Going ahead to step 6:
393 divided by 86 is 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 8044.0
Subtract 344 from 393 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
86 goes into 490 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 8044.5
Deduct 430 from 490 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.

Advancing to step 8:
If we divide 600 by 86, we get 6 and a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 8044.56
Subtracting 516 from 600 leaves us 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.

Let's proceed to step 9:
840 divided by 86 is 9 with a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 8044.569
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
660 divided by 86 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 8044.5697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
If we divide 580 by 86, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 8044.56976
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
640 divided by 86 is 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 8044.569767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
When dividing 380 by 86, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 8044.5697674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 86, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 8044.56976744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 8044.56976744 and a remainder of 1.6e-08.
