We look at the division of 675921 by 35 
The aim is to understand the frequency of 35 in 675921.

On to step 1:
If we divide 6 by 35, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 35

Let's proceed to step 2:
67 divided by 35 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 32 after subtracting 35 from 67.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 35

Let's proceed to step 3:
35 goes into 325 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 315 from 325, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 35

Advancing to step 4:
When dividing 109 by 35, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 193.0
Subtract 105 from 109 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 35

On to step 5:
When dividing 42 by 35, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1931.0
Subtract 35 from 42 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 35

Let's proceed to step 6:
35 can be fit into 71 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 19312.0
If we subtract 70 from 71, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 35, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19312.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 35 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 19312.02
If we subtract 70 from 100, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
If we divide 300 by 35, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 19312.028
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 35, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 19312.0285
Subtract 175 from 200 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
250 divided by 35 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 19312.02857
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.

Let's proceed to step 12:
The number 35 fits into 50 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 19312.028571
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.

Moving on to step 13:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 19312.0285714
Deduct 140 from 150 and we're left 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.

Going ahead to step 14:
35 goes into 100 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 19312.02857142
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.

Our division results in 19312.02857142 with a remaining 3e-08.
