57123670 ÷ 355 
The aim is to understand the frequency of 355 in 57123670.

Moving on to step 1:
5 divided by 355 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 355

Going ahead to step 2:
355 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 355

Step 3:
The number 355 fits into 571 1 times, leaving a remainder of 216.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 355 from 571 leaves us with 216.
Grab the next digit (2) from the dividend, add it to 216, then carry on: 2162 / 355

Let's proceed to step 4:
The number 355 fits into 2162 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2130 from 2162, we get 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 355

Let's proceed to step 5:
355 goes into 323 0 times with a remainder of 323.
Write down 0 as next digit of the result. 
Result so far: 160.0
If we subtract 0 from 323, we get 323.
Take the next digit (6) from the dividend and append it to 323, then repeat: 3236 / 355

Moving on to step 6:
The number 355 fits into 3236 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 1609.0
The remainder is 41 after subtracting 3195 from 3236.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 355

Advancing to step 7:
When dividing 417 by 355, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 16091.0
If we take 355 away from 417, we end up with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 355

Moving on to step 8:
If we divide 620 by 355, we get 1 and a remainder of 265.
Put 1 as the next digit of the answer. 
Result so far: 160911.0
Subtract 355 from 620 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 9:
The number 355 fits into 2650 7 times, leaving a remainder of 165.
Record the quotient 7 as the next digit in the result. 
Result so far: 160911.7
The remainder is 165 after subtracting 2485 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
355 can be fit into 1650 4 times, resulting in a remainder of 230.
The next digit of our result is 4. 
Result so far: 160911.74
Subtract 1420 from 1650 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 11:
355 can be fit into 2300 6 times, resulting in a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 160911.746
Subtracting 2130 from 2300 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 12:
355 can be fit into 1700 4 times, resulting in a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 160911.7464
The remainder is 280 after subtracting 1420 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 13:
2800 divided by 355 is 7 with a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 160911.74647
Deduct 2485 from 2800 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 14:
355 goes into 3150 8 times with a remainder of 310.
The number 8 becomes the next digit in our result. 
Result so far: 160911.746478
If we take 2840 away from 3150, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
3100 divided by 355 is 8 with a remainder of 260.
Put 8 as the next digit of the answer. 
Result so far: 160911.7464788
If we subtract 2840 from 3100, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 160911.7464788, with a leftover of 2.6e-06.
