We're dividing 91638057 by 35 
The aim is to understand the frequency of 35 in 91638057.

Advancing to step 1:
35 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 35

Going ahead to step 2:
If we divide 91 by 35, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 70 away from 91, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 35

Step 3:
When dividing 216 by 35, we get 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 6 after subtracting 210 from 216.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 35

Advancing to step 4:
35 goes into 63 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 261.0
If we take 35 away from 63, we end up with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 35

Step 5:
288 divided by 35 is 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2618.0
If we take 280 away from 288, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 35

Advancing to step 6:
When dividing 80 by 35, we get 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 26182.0
If we subtract 70 from 80, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 35

Moving on to step 7:
When dividing 105 by 35, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 261823.0
Subtracting 105 from 105 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 35

Advancing to step 8:
When dividing 7 by 35, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 2618230.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
If we divide 70 by 35, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2618230.2
Deduct 70 from 70 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 35 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2618230.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
35 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2618230.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 2618230.2 with a remaining 0.0.
