644374 divided by 35 
The aim is to understand the frequency of 35 in 644374.

Moving on to step 1:
The number 35 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 35

Advancing to step 2:
64 divided by 35 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 35 away from 64, we end up with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 35

On to step 3:
294 divided by 35 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 280 from 294, we get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 35

Going ahead to step 4:
If we divide 143 by 35, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 184.0
Subtract 140 from 143 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 35

Advancing to step 5:
35 can be fit into 37 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1841.0
Deduct 35 from 37 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 35

Going ahead to step 6:
35 can be fit into 24 0 times, resulting in a remainder of 24.
The next digit of our result is 0. 
Result so far: 18410.0
Subtracting 0 from 24 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 35, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 18410.6
Deduct 210 from 240 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.

Advancing to step 8:
300 divided by 35 is 8 with a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 18410.68
Deduct 280 from 300 and we're left 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.

Step 9:
When dividing 200 by 35, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 18410.685
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.

Step 10:
35 can be fit into 250 7 times, resulting in a remainder of 5.
The next digit of our result is 7. 
Result so far: 18410.6857
If we subtract 245 from 250, we get 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 11:
35 can be fit into 50 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 18410.68571
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 12:
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: 18410.685714
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 13:
If we divide 100 by 35, we get 2 and a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 18410.6857142
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.

Step 14:
35 can be fit into 300 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 18410.68571428
If we subtract 280 from 300, we 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.

The final result is 18410.68571428 with a remainder of 2e-08.
