We divide 85710420 by 488
The aim is to understand the frequency of 488 in 85710420.

Moving on to step 1:
If we divide 8 by 488, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 488

Moving on to step 2:
When dividing 85 by 488, we get 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (7) from the dividend and append it to 85, then repeat: 857 / 488

Moving on to step 3:
If we divide 857 by 488, we get 1 and a remainder of 369.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 488 away from 857, we end up with 369.
Include the next digit (1) from the dividend after 369, then repeat: 3691 / 488

Step 4:
3691 divided by 488 is 7 with a remainder of 275.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtracting 3416 from 3691 leaves us with 275.
Include the next digit (0) from the dividend after 275, then repeat: 2750 / 488

Advancing to step 5:
2750 divided by 488 is 5 with a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
The remainder is 310 after subtracting 2440 from 2750.
Fetch the next digit (4) from the dividend, attach it to 310 and continue: 3104 / 488

Advancing to step 6:
If we divide 3104 by 488, we get 6 and a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 1756.0
Subtract 2928 from 3104 to get 176.
Grab the next digit (2) from the dividend, add it to 176, then carry on: 1762 / 488

Advancing to step 7:
488 can be fit into 1762 3 times, resulting in a remainder of 298.
Write down 3 as next digit of the result. 
Result so far: 17563.0
Subtracting 1464 from 1762 leaves us with 298.
Include the next digit (0) from the dividend after 298, then repeat: 2980 / 488

Going ahead to step 8:
The number 488 fits into 2980 6 times, leaving a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 175636.0
Deduct 2928 from 2980 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
520 divided by 488 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 175636.1
Subtract 488 from 520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
488 can be fit into 320 0 times, resulting in a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 175636.1
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 11:
If we divide 3200 by 488, we get 6 and a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 175636.106
Subtract 2928 from 3200 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 12:
The number 488 fits into 2720 5 times, leaving a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 175636.1065
If we subtract 2440 from 2720, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
The number 488 fits into 2800 5 times, leaving a remainder of 360.
The next digit of our result is 5. 
Result so far: 175636.10655
If we take 2440 away from 2800, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final outcome is 175636.10655, with a leftover of 0.00036.
