We look at the division of 31902303 by 570 
The aim is to understand the frequency of 570 in 31902303.

Advancing to step 1:
570 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 570

Advancing to step 2:
The number 570 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 570

Going ahead to step 3:
When dividing 319 by 570, we get 0 with a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 319 and we're left with 319.
Grab the next digit (0) from the dividend, add it to 319, then carry on: 3190 / 570

Step 4:
570 can be fit into 3190 5 times, resulting in a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 340 after subtracting 2850 from 3190.
Include the next digit (2) from the dividend after 340, then repeat: 3402 / 570

Step 5:
3402 divided by 570 is 5 with a remainder of 552.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 2850 from 3402 leaves us with 552.
Grab the next digit (3) from the dividend, add it to 552, then carry on: 5523 / 570

Advancing to step 6:
If we divide 5523 by 570, we get 9 and a remainder of 393.
The next digit of our result is 9. 
Result so far: 559.0
Subtracting 5130 from 5523 leaves us with 393.
Include the next digit (0) from the dividend after 393, then repeat: 3930 / 570

Moving on to step 7:
570 can be fit into 3930 6 times, resulting in a remainder of 510.
The next digit of our result is 6. 
Result so far: 5596.0
Deduct 3420 from 3930 and we're left with 510.
Grab the next digit (3) from the dividend, add it to 510, then carry on: 5103 / 570

Let's proceed to step 8:
When dividing 5103 by 570, we get 8 with a remainder of 543.
The number 8 becomes the next digit in our result. 
Result so far: 55968.0
Subtracting 4560 from 5103 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Step 9:
The number 570 fits into 5430 9 times, leaving a remainder of 300.
The number 9 becomes the next digit in our result. 
Result so far: 55968.9
Subtracting 5130 from 5430 leaves us 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.

Going ahead to step 10:
When dividing 3000 by 570, we get 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 55968.95
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.

On to step 11:
1500 divided by 570 is 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 55968.952
Subtracting 1140 from 1500 leaves us 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 12:
The number 570 fits into 3600 6 times, leaving a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 55968.9526
If we take 3420 away from 3600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
570 can be fit into 1800 3 times, resulting in a remainder of 90.
Put 3 as the next digit of the answer. 
Result so far: 55968.95263
If we subtract 1710 from 1800, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 14:
570 goes into 900 1 times with a remainder of 330.
The next digit of our result is 1. 
Result so far: 55968.952631
If we take 570 away from 900, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 15:
570 goes into 3300 5 times with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 55968.9526315
Deduct 2850 from 3300 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 16:
570 goes into 4500 7 times with a remainder of 510.
Put 7 as the next digit of the answer. 
Result so far: 55968.95263157
If we subtract 3990 from 4500, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

The final result is 55968.95263157 with a remainder of 5.1e-07.
