We look at the division of 93858271 by 604 
The aim is to understand the frequency of 604 in 93858271.

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
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 604

On to step 2:
93 divided by 604 is 0 with a remainder of 93.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Bring next digit (8) of the dividend behind the 93 and repeat the process: 938 / 604

Going ahead to step 3:
604 goes into 938 1 times with a remainder of 334.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 604 from 938 and we're left with 334.
Fetch the next digit (5) from the dividend, attach it to 334 and continue: 3345 / 604

On to step 4:
604 goes into 3345 5 times with a remainder of 325.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 325 after subtracting 3020 from 3345.
Fetch the next digit (8) from the dividend, attach it to 325 and continue: 3258 / 604

Step 5:
604 can be fit into 3258 5 times, resulting in a remainder of 238.
Write down 5 as next digit of the result. 
Result so far: 155.0
The remainder is 238 after subtracting 3020 from 3258.
Bring next digit (2) of the dividend behind the 238 and repeat the process: 2382 / 604

Going ahead to step 6:
2382 divided by 604 is 3 with a remainder of 570.
Put 3 as the next digit of the answer. 
Result so far: 1553.0
Deduct 1812 from 2382 and we're left with 570.
Fetch the next digit (7) from the dividend, attach it to 570 and continue: 5707 / 604

Advancing to step 7:
5707 divided by 604 is 9 with a remainder of 271.
Put 9 as the next digit of the answer. 
Result so far: 15539.0
The remainder is 271 after subtracting 5436 from 5707.
Fetch the next digit (1) from the dividend, attach it to 271 and continue: 2711 / 604

Advancing to step 8:
If we divide 2711 by 604, we get 4 and a remainder of 295.
Use 4 as the next digit of our solution. 
Result so far: 155394.0
Subtract 2416 from 2711 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 9:
604 goes into 2950 4 times with a remainder of 534.
Record the quotient 4 as the next digit in the result. 
Result so far: 155394.4
Deduct 2416 from 2950 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Going ahead to step 10:
The number 604 fits into 5340 8 times, leaving a remainder of 508.
Use 8 as the next digit of our solution. 
Result so far: 155394.48
Subtracting 4832 from 5340 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 11:
If we divide 5080 by 604, we get 8 and a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 155394.488
The remainder is 248 after subtracting 4832 from 5080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 155394.488 and a remainder of 0.0248.
