We divide 90406335 by 566
The aim is to understand the frequency of 566 in 90406335.

Moving on to step 1:
566 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 566

Step 2:
The number 566 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 566

Advancing to step 3:
The number 566 fits into 904 1 times, leaving a remainder of 338.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 338 after subtracting 566 from 904.
Fetch the next digit (0) from the dividend, attach it to 338 and continue: 3380 / 566

Going ahead to step 4:
3380 divided by 566 is 5 with a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2830 from 3380 leaves us with 550.
Fetch the next digit (6) from the dividend, attach it to 550 and continue: 5506 / 566

Going ahead to step 5:
566 goes into 5506 9 times with a remainder of 412.
Use 9 as the next digit of our solution. 
Result so far: 159.0
If we subtract 5094 from 5506, we get 412.
Fetch the next digit (3) from the dividend, attach it to 412 and continue: 4123 / 566

On to step 6:
If we divide 4123 by 566, we get 7 and a remainder of 161.
Record the quotient 7 as the next digit in the result. 
Result so far: 1597.0
Subtract 3962 from 4123 to get 161.
Take the next digit (3) from the dividend and append it to 161, then repeat: 1613 / 566

Moving on to step 7:
566 can be fit into 1613 2 times, resulting in a remainder of 481.
Record the quotient 2 as the next digit in the result. 
Result so far: 15972.0
Subtracting 1132 from 1613 leaves us with 481.
Fetch the next digit (5) from the dividend, attach it to 481 and continue: 4815 / 566

Moving on to step 8:
When dividing 4815 by 566, we get 8 with a remainder of 287.
The next digit of our result is 8. 
Result so far: 159728.0
The remainder is 287 after subtracting 4528 from 4815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 9:
566 goes into 2870 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 159728.5
Subtract 2830 from 2870 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
566 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 159728.5
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
566 can be fit into 4000 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 159728.507
The remainder is 38 after subtracting 3962 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
380 divided by 566 is 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 159728.507
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
The number 566 fits into 3800 6 times, leaving a remainder of 404.
Put 6 as the next digit of the answer. 
Result so far: 159728.50706
The remainder is 404 after subtracting 3396 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 14:
4040 divided by 566 is 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 159728.507067
Subtracting 3962 from 4040 leaves us 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.

On to step 15:
566 can be fit into 780 1 times, resulting in a remainder of 214.
The next digit of our result is 1. 
Result so far: 159728.5070671
Deduct 566 from 780 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 16:
When dividing 2140 by 566, we get 3 with a remainder of 442.
Use 3 as the next digit of our solution. 
Result so far: 159728.50706713
Subtract 1698 from 2140 to get 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

After the division, we end up with 159728.50706713 and a remainder of 4.42e-07.
