Let's divide 35915670 by 670
The aim is to understand the frequency of 670 in 35915670.

Going ahead to step 1:
If we divide 3 by 670, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 670

On to step 2:
When dividing 35 by 670, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 670

Step 3:
670 goes into 359 0 times with a remainder of 359.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 359 after subtracting 0 from 359.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 670

Moving on to step 4:
3591 divided by 670 is 5 with a remainder of 241.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 3350 from 3591 leaves us with 241.
Fetch the next digit (5) from the dividend, attach it to 241 and continue: 2415 / 670

On to step 5:
670 goes into 2415 3 times with a remainder of 405.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 2010 from 2415 to get 405.
Fetch the next digit (6) from the dividend, attach it to 405 and continue: 4056 / 670

Step 6:
670 goes into 4056 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 536.0
Deduct 4020 from 4056 and we're left with 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 670

Moving on to step 7:
The number 670 fits into 367 0 times, leaving a remainder of 367.
Record the quotient 0 as the next digit in the result. 
Result so far: 5360.0
The remainder is 367 after subtracting 0 from 367.
Fetch the next digit (0) from the dividend, attach it to 367 and continue: 3670 / 670

Going ahead to step 8:
If we divide 3670 by 670, we get 5 and a remainder of 320.
The next digit of our result is 5. 
Result so far: 53605.0
The remainder is 320 after subtracting 3350 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 9:
670 can be fit into 3200 4 times, resulting in a remainder of 520.
Write down 4 as next digit of the result. 
Result so far: 53605.4
If we take 2680 away from 3200, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 10:
670 can be fit into 5200 7 times, resulting in a remainder of 510.
Use 7 as the next digit of our solution. 
Result so far: 53605.47
Subtract 4690 from 5200 to get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 11:
If we divide 5100 by 670, we get 7 and a remainder of 410.
The number 7 becomes the next digit in our result. 
Result so far: 53605.477
The remainder is 410 after subtracting 4690 from 5100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

The final result is 53605.477 with a remainder of 0.041.
