We're dividing 17006983 by 604 
The aim is to understand the frequency of 604 in 17006983.

Advancing to step 1:
604 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 604

Going ahead to step 2:
604 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 604

Going ahead to step 3:
When dividing 170 by 604, we get 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 170 leaves us with 170.
Bring next digit (0) of the dividend behind the 170 and repeat the process: 1700 / 604

Advancing to step 4:
1700 divided by 604 is 2 with a remainder of 492.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1208 from 1700 leaves us with 492.
Grab the next digit (6) from the dividend, add it to 492, then carry on: 4926 / 604

On to step 5:
604 goes into 4926 8 times with a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 4832 from 4926 leaves us with 94.
Append the next digit (9) from the dividend to 94 and continue with: 949 / 604

Step 6:
If we divide 949 by 604, we get 1 and a remainder of 345.
Put 1 as the next digit of the answer. 
Result so far: 281.0
Subtracting 604 from 949 leaves us with 345.
Grab the next digit (8) from the dividend, add it to 345, then carry on: 3458 / 604

Advancing to step 7:
The number 604 fits into 3458 5 times, leaving a remainder of 438.
Use 5 as the next digit of our solution. 
Result so far: 2815.0
If we take 3020 away from 3458, we end up with 438.
Bring next digit (3) of the dividend behind the 438 and repeat the process: 4383 / 604

Advancing to step 8:
When dividing 4383 by 604, we get 7 with a remainder of 155.
Use 7 as the next digit of our solution. 
Result so far: 28157.0
The remainder is 155 after subtracting 4228 from 4383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
1550 divided by 604 is 2 with a remainder of 342.
Use 2 as the next digit of our solution. 
Result so far: 28157.2
Subtract 1208 from 1550 to get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 10:
604 can be fit into 3420 5 times, resulting in a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 28157.25
If we subtract 3020 from 3420, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 11:
604 goes into 4000 6 times with a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 28157.256
Deduct 3624 from 4000 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Going ahead to step 12:
When dividing 3760 by 604, we get 6 with a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 28157.2566
Subtracting 3624 from 3760 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Our division results in 28157.2566 with a remaining 0.00136.
