We look at the division of 31854142 by 607 
The aim is to understand the frequency of 607 in 31854142.

Let's proceed to step 1:
If we divide 3 by 607, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 607

Let's proceed to step 2:
607 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 607

Step 3:
If we divide 318 by 607, we get 0 and a remainder of 318.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 318 to get 318.
Grab the next digit (5) from the dividend, add it to 318, then carry on: 3185 / 607

Advancing to step 4:
When dividing 3185 by 607, we get 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3035 from 3185 leaves us with 150.
Include the next digit (4) from the dividend after 150, then repeat: 1504 / 607

Advancing to step 5:
1504 divided by 607 is 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 290 after subtracting 1214 from 1504.
Grab the next digit (1) from the dividend, add it to 290, then carry on: 2901 / 607

Moving on to step 6:
If we divide 2901 by 607, we get 4 and a remainder of 473.
The next digit of our result is 4. 
Result so far: 524.0
The remainder is 473 after subtracting 2428 from 2901.
Bring next digit (4) of the dividend behind the 473 and repeat the process: 4734 / 607

Moving on to step 7:
If we divide 4734 by 607, we get 7 and a remainder of 485.
Record the quotient 7 as the next digit in the result. 
Result so far: 5247.0
Deduct 4249 from 4734 and we're left with 485.
Bring next digit (2) of the dividend behind the 485 and repeat the process: 4852 / 607

Going ahead to step 8:
When dividing 4852 by 607, we get 7 with a remainder of 603.
The next digit of our result is 7. 
Result so far: 52477.0
Subtract 4249 from 4852 to get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Let's proceed to step 9:
607 can be fit into 6030 9 times, resulting in a remainder of 567.
The number 9 becomes the next digit in our result. 
Result so far: 52477.9
Subtracting 5463 from 6030 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 10:
5670 divided by 607 is 9 with a remainder of 207.
The next digit of our result is 9. 
Result so far: 52477.99
If we subtract 5463 from 5670, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The quotient of the division is 52477.99, and the remainder is 0.207.
