We're dividing 73817612 by 604 
The aim is to understand the frequency of 604 in 73817612.

Going ahead to step 1:
604 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 604

Moving on to step 2:
The number 604 fits into 73 0 times, leaving a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 604

Going ahead to step 3:
738 divided by 604 is 1 with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 134 after subtracting 604 from 738.
Append the next digit (1) from the dividend to 134 and continue with: 1341 / 604

Going ahead to step 4:
604 goes into 1341 2 times with a remainder of 133.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 133 after subtracting 1208 from 1341.
Append the next digit (7) from the dividend to 133 and continue with: 1337 / 604

Advancing to step 5:
604 goes into 1337 2 times with a remainder of 129.
Write down 2 as next digit of the result. 
Result so far: 122.0
Subtracting 1208 from 1337 leaves us with 129.
Take the next digit (6) from the dividend and append it to 129, then repeat: 1296 / 604

Let's proceed to step 6:
When dividing 1296 by 604, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 1222.0
Subtracting 1208 from 1296 leaves us with 88.
Include the next digit (1) from the dividend after 88, then repeat: 881 / 604

Step 7:
The number 604 fits into 881 1 times, leaving a remainder of 277.
Use 1 as the next digit of our solution. 
Result so far: 12221.0
Deduct 604 from 881 and we're left with 277.
Take the next digit (2) from the dividend and append it to 277, then repeat: 2772 / 604

Moving on to step 8:
When dividing 2772 by 604, we get 4 with a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 122214.0
Subtract 2416 from 2772 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 9:
3560 divided by 604 is 5 with a remainder of 540.
The number 5 becomes the next digit in our result. 
Result so far: 122214.5
If we subtract 3020 from 3560, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 10:
604 can be fit into 5400 8 times, resulting in a remainder of 568.
Put 8 as the next digit of the answer. 
Result so far: 122214.58
The remainder is 568 after subtracting 4832 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 11:
604 goes into 5680 9 times with a remainder of 244.
Use 9 as the next digit of our solution. 
Result so far: 122214.589
Subtract 5436 from 5680 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 12:
604 goes into 2440 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 122214.5894
Subtract 2416 from 2440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
If we divide 240 by 604, we get 0 and a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 122214.5894
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
2400 divided by 604 is 3 with a remainder of 588.
Write down 3 as next digit of the result. 
Result so far: 122214.589403
Subtract 1812 from 2400 to get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 15:
604 goes into 5880 9 times with a remainder of 444.
The number 9 becomes the next digit in our result. 
Result so far: 122214.5894039
Subtract 5436 from 5880 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 16:
604 can be fit into 4440 7 times, resulting in a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 122214.58940397
If we take 4228 away from 4440, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final outcome is 122214.58940397, with a leftover of 2.12e-07.
