99675507 divided by 604 
The aim is to understand the frequency of 604 in 99675507.

Going ahead to step 1:
If we divide 9 by 604, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 604

Step 2:
99 divided by 604 is 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Include the next digit (6) from the dividend after 99, then repeat: 996 / 604

Going ahead to step 3:
The number 604 fits into 996 1 times, leaving a remainder of 392.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 604 from 996 and we're left with 392.
Grab the next digit (7) from the dividend, add it to 392, then carry on: 3927 / 604

Step 4:
If we divide 3927 by 604, we get 6 and a remainder of 303.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 3624 from 3927, we get 303.
Include the next digit (5) from the dividend after 303, then repeat: 3035 / 604

Step 5:
604 can be fit into 3035 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 165.0
Deduct 3020 from 3035 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 604

On to step 6:
The number 604 fits into 155 0 times, leaving a remainder of 155.
Write down 0 as next digit of the result. 
Result so far: 1650.0
The remainder is 155 after subtracting 0 from 155.
Append the next digit (0) from the dividend to 155 and continue with: 1550 / 604

Going ahead to step 7:
604 goes into 1550 2 times with a remainder of 342.
Write down 2 as next digit of the result. 
Result so far: 16502.0
Subtracting 1208 from 1550 leaves us with 342.
Append the next digit (7) from the dividend to 342 and continue with: 3427 / 604

Advancing to step 8:
604 can be fit into 3427 5 times, resulting in a remainder of 407.
The number 5 becomes the next digit in our result. 
Result so far: 165025.0
Deduct 3020 from 3427 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Let's proceed to step 9:
When dividing 4070 by 604, we get 6 with a remainder of 446.
Put 6 as the next digit of the answer. 
Result so far: 165025.6
Subtract 3624 from 4070 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Advancing to step 10:
The number 604 fits into 4460 7 times, leaving a remainder of 232.
The number 7 becomes the next digit in our result. 
Result so far: 165025.67
Subtract 4228 from 4460 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 11:
604 goes into 2320 3 times with a remainder of 508.
The number 3 becomes the next digit in our result. 
Result so far: 165025.673
If we subtract 1812 from 2320, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 12:
The number 604 fits into 5080 8 times, leaving a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 165025.6738
If we subtract 4832 from 5080, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 13:
604 can be fit into 2480 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 165025.67384
Subtracting 2416 from 2480 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
The number 604 fits into 640 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 165025.673841
Deduct 604 from 640 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 15:
604 can be fit into 360 0 times, resulting in a remainder of 360.
The next digit of our result is 0. 
Result so far: 165025.673841
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 16:
3600 divided by 604 is 5 with a remainder of 580.
Use 5 as the next digit of our solution. 
Result so far: 165025.67384105
Deduct 3020 from 3600 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

After the division, we end up with 165025.67384105 and a remainder of 5.8e-07.
