We divide 18638 by 35
The aim is to understand the frequency of 35 in 18638.

Advancing to step 1:
35 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 35

On to step 2:
The number 35 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 35

Going ahead to step 3:
35 goes into 186 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 175 from 186 and we're left with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 35

On to step 4:
If we divide 113 by 35, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtract 105 from 113 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 35

Advancing to step 5:
88 divided by 35 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 532.0
Deduct 70 from 88 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 6:
When dividing 180 by 35, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 532.5
Deduct 175 from 180 and we're left 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 7:
When dividing 50 by 35, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 532.51
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 8:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 532.514
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.

Moving on to step 9:
When dividing 100 by 35, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 532.5142
If we take 70 away from 100, we end up 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 10:
35 can be fit into 300 8 times, resulting in a remainder of 20.
The next digit of our result is 8. 
Result so far: 532.51428
Subtract 280 from 300 to get 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 11:
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: 532.514285
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.

Going ahead to step 12:
250 divided by 35 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 532.5142857
Deduct 245 from 250 and we're left 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 13:
35 can be fit into 50 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 532.51428571
Subtracting 35 from 50 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.

The final result is 532.51428571 with a remainder of 1.5e-08.
