We look at the division of 81717608 by 46 
The aim is to understand the frequency of 46 in 81717608.

Step 1:
If we divide 8 by 46, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 46

Moving on to step 2:
The number 46 fits into 81 1 times, leaving a remainder of 35.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 46 from 81 leaves us with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 46

Going ahead to step 3:
357 divided by 46 is 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 322 from 357, we get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 46

On to step 4:
46 can be fit into 351 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 177.0
Subtract 322 from 351 to get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 46

Going ahead to step 5:
46 goes into 297 6 times with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 1776.0
Subtract 276 from 297 to get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 46

Step 6:
The number 46 fits into 216 4 times, leaving a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 17764.0
Subtracting 184 from 216 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 46

Let's proceed to step 7:
When dividing 320 by 46, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 177646.0
The remainder is 44 after subtracting 276 from 320.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 46

Moving on to step 8:
The number 46 fits into 448 9 times, leaving a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 1776469.0
Deduct 414 from 448 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
46 can be fit into 340 7 times, resulting in a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 1776469.7
Deduct 322 from 340 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
When dividing 180 by 46, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1776469.73
Subtracting 138 from 180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
The number 46 fits into 420 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1776469.739
Deduct 414 from 420 and we're left 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.

Going ahead to step 12:
46 can be fit into 60 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1776469.7391
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
If we divide 140 by 46, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1776469.73913
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
When dividing 20 by 46, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1776469.73913
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 15:
The number 46 fits into 200 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1776469.7391304
If we take 184 away from 200, we end up 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.

Step 16:
The number 46 fits into 160 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 1776469.73913043
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 1776469.73913043 and a remainder of 2.2e-08.
