Let's divide 88173590 by 566
The aim is to understand the frequency of 566 in 88173590.

Step 1:
If we divide 8 by 566, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 566

Going ahead to step 2:
566 can be fit into 88 0 times, resulting in a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Grab the next digit (1) from the dividend, add it to 88, then carry on: 881 / 566

Moving on to step 3:
566 can be fit into 881 1 times, resulting in a remainder of 315.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 566 from 881 leaves us with 315.
Include the next digit (7) from the dividend after 315, then repeat: 3157 / 566

Advancing to step 4:
3157 divided by 566 is 5 with a remainder of 327.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2830 away from 3157, we end up with 327.
Bring next digit (3) of the dividend behind the 327 and repeat the process: 3273 / 566

On to step 5:
566 goes into 3273 5 times with a remainder of 443.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Deduct 2830 from 3273 and we're left with 443.
Append the next digit (5) from the dividend to 443 and continue with: 4435 / 566

Going ahead to step 6:
The number 566 fits into 4435 7 times, leaving a remainder of 473.
Use 7 as the next digit of our solution. 
Result so far: 1557.0
If we take 3962 away from 4435, we end up with 473.
Bring next digit (9) of the dividend behind the 473 and repeat the process: 4739 / 566

Advancing to step 7:
4739 divided by 566 is 8 with a remainder of 211.
Use 8 as the next digit of our solution. 
Result so far: 15578.0
The remainder is 211 after subtracting 4528 from 4739.
Append the next digit (0) from the dividend to 211 and continue with: 2110 / 566

Step 8:
566 can be fit into 2110 3 times, resulting in a remainder of 412.
Use 3 as the next digit of our solution. 
Result so far: 155783.0
Deduct 1698 from 2110 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 9:
566 goes into 4120 7 times with a remainder of 158.
Put 7 as the next digit of the answer. 
Result so far: 155783.7
The remainder is 158 after subtracting 3962 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 10:
1580 divided by 566 is 2 with a remainder of 448.
Use 2 as the next digit of our solution. 
Result so far: 155783.72
Subtract 1132 from 1580 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 11:
The number 566 fits into 4480 7 times, leaving a remainder of 518.
Write down 7 as next digit of the result. 
Result so far: 155783.727
If we take 3962 away from 4480, we end up with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Advancing to step 12:
If we divide 5180 by 566, we get 9 and a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 155783.7279
If we take 5094 away from 5180, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 13:
860 divided by 566 is 1 with a remainder of 294.
The number 1 becomes the next digit in our result. 
Result so far: 155783.72791
If we subtract 566 from 860, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 14:
2940 divided by 566 is 5 with a remainder of 110.
Use 5 as the next digit of our solution. 
Result so far: 155783.727915
Subtracting 2830 from 2940 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 15:
If we divide 1100 by 566, we get 1 and a remainder of 534.
The next digit of our result is 1. 
Result so far: 155783.7279151
If we take 566 away from 1100, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 16:
If we divide 5340 by 566, we get 9 and a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 155783.72791519
If we take 5094 away from 5340, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

The final result is 155783.72791519 with a remainder of 2.46e-07.
