45553880 divided by 86 
The aim is to understand the frequency of 86 in 45553880.

On to step 1:
When dividing 4 by 86, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 86

Advancing to step 2:
86 can be fit into 45 0 times, resulting in a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 86

Let's proceed to step 3:
455 divided by 86 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 430 from 455 and we're left with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 86

Moving on to step 4:
86 can be fit into 255 2 times, resulting in a remainder of 83.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 172 from 255 leaves us with 83.
Include the next digit (3) from the dividend after 83, then repeat: 833 / 86

Step 5:
If we divide 833 by 86, we get 9 and a remainder of 59.
The next digit of our result is 9. 
Result so far: 529.0
Subtracting 774 from 833 leaves us with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 86

Advancing to step 6:
598 divided by 86 is 6 with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 5296.0
If we subtract 516 from 598, we get 82.
Grab the next digit (8) from the dividend, add it to 82, then carry on: 828 / 86

Step 7:
86 can be fit into 828 9 times, resulting in a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 52969.0
Subtracting 774 from 828 leaves us with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 86

On to step 8:
86 goes into 540 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 529696.0
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.

Let's proceed to step 9:
When dividing 240 by 86, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 529696.2
If we subtract 172 from 240, we get 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 10:
86 goes into 680 7 times with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 529696.27
Deduct 602 from 680 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 11:
If we divide 780 by 86, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 529696.279
If we subtract 774 from 780, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
86 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 529696.279
If we take 0 away from 60, we end up 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.

Moving on to step 13:
When dividing 600 by 86, we get 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 529696.27906
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 14:
86 goes into 840 9 times with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 529696.279069
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.

Moving on to step 15:
86 can be fit into 660 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 529696.2790697
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 16:
When dividing 580 by 86, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 529696.27906976
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 529696.27906976 with a remaining 6.4e-08.
