We look at the division of 86354334 by 604 
The aim is to understand the frequency of 604 in 86354334.

Moving on to step 1:
When dividing 8 by 604, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 604

On to step 2:
If we divide 86 by 604, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 604

On to step 3:
If we divide 863 by 604, we get 1 and a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 604 away from 863, we end up with 259.
Bring next digit (5) of the dividend behind the 259 and repeat the process: 2595 / 604

Moving on to step 4:
2595 divided by 604 is 4 with a remainder of 179.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 2416 away from 2595, we end up with 179.
Fetch the next digit (4) from the dividend, attach it to 179 and continue: 1794 / 604

Let's proceed to step 5:
1794 divided by 604 is 2 with a remainder of 586.
The next digit of our result is 2. 
Result so far: 142.0
If we take 1208 away from 1794, we end up with 586.
Include the next digit (3) from the dividend after 586, then repeat: 5863 / 604

Step 6:
When dividing 5863 by 604, we get 9 with a remainder of 427.
The number 9 becomes the next digit in our result. 
Result so far: 1429.0
Deduct 5436 from 5863 and we're left with 427.
Take the next digit (3) from the dividend and append it to 427, then repeat: 4273 / 604

Step 7:
604 can be fit into 4273 7 times, resulting in a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 14297.0
Deduct 4228 from 4273 and we're left with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 604

Advancing to step 8:
454 divided by 604 is 0 with a remainder of 454.
Write down 0 as next digit of the result. 
Result so far: 142970.0
The remainder is 454 after subtracting 0 from 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 9:
The number 604 fits into 4540 7 times, leaving a remainder of 312.
Write down 7 as next digit of the result. 
Result so far: 142970.7
If we take 4228 away from 4540, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 10:
If we divide 3120 by 604, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 142970.75
Subtracting 3020 from 3120 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
1000 divided by 604 is 1 with a remainder of 396.
The next digit of our result is 1. 
Result so far: 142970.751
If we take 604 away from 1000, we end up with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 12:
When dividing 3960 by 604, we get 6 with a remainder of 336.
Put 6 as the next digit of the answer. 
Result so far: 142970.7516
If we take 3624 away from 3960, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Moving on to step 13:
When dividing 3360 by 604, we get 5 with a remainder of 340.
Use 5 as the next digit of our solution. 
Result so far: 142970.75165
Subtract 3020 from 3360 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
3400 divided by 604 is 5 with a remainder of 380.
Record the quotient 5 as the next digit in the result. 
Result so far: 142970.751655
If we subtract 3020 from 3400, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 142970.751655 with a remainder of 3.8e-05.
