13590883 ÷ 670 
The aim is to understand the frequency of 670 in 13590883.

Going ahead to step 1:
1 divided by 670 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 670

Let's proceed to step 2:
If we divide 13 by 670, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 670

Let's proceed to step 3:
When dividing 135 by 670, we get 0 with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 135 to get 135.
Grab the next digit (9) from the dividend, add it to 135, then carry on: 1359 / 670

Going ahead to step 4:
670 can be fit into 1359 2 times, resulting in a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1340 from 1359 and we're left with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 670

Let's proceed to step 5:
When dividing 190 by 670, we get 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 190, we get 190.
Take the next digit (8) from the dividend and append it to 190, then repeat: 1908 / 670

Advancing to step 6:
670 can be fit into 1908 2 times, resulting in a remainder of 568.
The next digit of our result is 2. 
Result so far: 202.0
Subtracting 1340 from 1908 leaves us with 568.
Take the next digit (8) from the dividend and append it to 568, then repeat: 5688 / 670

Going ahead to step 7:
When dividing 5688 by 670, we get 8 with a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 2028.0
The remainder is 328 after subtracting 5360 from 5688.
Fetch the next digit (3) from the dividend, attach it to 328 and continue: 3283 / 670

On to step 8:
670 can be fit into 3283 4 times, resulting in a remainder of 603.
Write down 4 as next digit of the result. 
Result so far: 20284.0
Deduct 2680 from 3283 and we're left with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Moving on to step 9:
When dividing 6030 by 670, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 20284.9
Subtract 6030 from 6030 to get 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:
The number 670 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20284.9
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:
670 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20284.9
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.

The final result is 20284.9 with a remainder of 0.0.
