We look at the division of 31886109 by 570 
The aim is to understand the frequency of 570 in 31886109.

Moving on to step 1:
When dividing 3 by 570, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 570

Let's proceed to step 2:
The number 570 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 570

Moving on to step 3:
When dividing 318 by 570, we get 0 with a remainder of 318.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 318, we end up with 318.
Grab the next digit (8) from the dividend, add it to 318, then carry on: 3188 / 570

Moving on to step 4:
570 can be fit into 3188 5 times, resulting in a remainder of 338.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2850 from 3188, we get 338.
Bring next digit (6) of the dividend behind the 338 and repeat the process: 3386 / 570

Advancing to step 5:
If we divide 3386 by 570, we get 5 and a remainder of 536.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we subtract 2850 from 3386, we get 536.
Append the next digit (1) from the dividend to 536 and continue with: 5361 / 570

Let's proceed to step 6:
If we divide 5361 by 570, we get 9 and a remainder of 231.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
If we subtract 5130 from 5361, we get 231.
Append the next digit (0) from the dividend to 231 and continue with: 2310 / 570

Moving on to step 7:
The number 570 fits into 2310 4 times, leaving a remainder of 30.
The next digit of our result is 4. 
Result so far: 5594.0
The remainder is 30 after subtracting 2280 from 2310.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 570

Going ahead to step 8:
570 goes into 309 0 times with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 55940.0
Subtract 0 from 309 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 9:
When dividing 3090 by 570, we get 5 with a remainder of 240.
Use 5 as the next digit of our solution. 
Result so far: 55940.5
If we take 2850 away from 3090, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
If we divide 2400 by 570, we get 4 and a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 55940.54
If we subtract 2280 from 2400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
1200 divided by 570 is 2 with a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 55940.542
Subtract 1140 from 1200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
If we divide 600 by 570, we get 1 and a remainder of 30.
The next digit of our result is 1. 
Result so far: 55940.5421
Deduct 570 from 600 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
If we divide 300 by 570, we get 0 and a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 55940.5421
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 14:
570 goes into 3000 5 times with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 55940.542105
The remainder is 150 after subtracting 2850 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
1500 divided by 570 is 2 with a remainder of 360.
Use 2 as the next digit of our solution. 
Result so far: 55940.5421052
If we take 1140 away from 1500, 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.

Going ahead to step 16:
If we divide 3600 by 570, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 55940.54210526
Subtract 3420 from 3600 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 55940.54210526 with a remaining 1.8e-07.
