Let's divide 631520 by 35
The aim is to understand the frequency of 35 in 631520.

Going ahead to step 1:
The number 35 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 35

Let's proceed to step 2:
When dividing 63 by 35, we get 1 with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 35 from 63, we get 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 35

Step 3:
The number 35 fits into 281 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 280 from 281 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 35

Going ahead to step 4:
If we divide 15 by 35, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 180.0
Subtract 0 from 15 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 35

Advancing to step 5:
When dividing 152 by 35, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1804.0
The remainder is 12 after subtracting 140 from 152.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 35

Let's proceed to step 6:
The number 35 fits into 120 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18043.0
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 35, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 18043.4
Subtracting 140 from 150 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 35, we get 2 and a remainder of 30.
The next digit of our result is 2. 
Result so far: 18043.42
Deduct 70 from 100 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.

Let's proceed to step 9:
If we divide 300 by 35, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 18043.428
The remainder is 20 after subtracting 280 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
35 goes into 200 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 18043.4285
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
35 goes into 250 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 18043.42857
Subtracting 245 from 250 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 35 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 18043.428571
The remainder is 15 after subtracting 35 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
35 goes into 150 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 18043.4285714
The remainder is 10 after subtracting 140 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
35 can be fit into 100 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 18043.42857142
Subtracting 70 from 100 leaves us 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.

The final outcome is 18043.42857142, with a leftover of 3e-08.
