We're dividing 52451815 by 704 
The aim is to understand the frequency of 704 in 52451815.

Let's proceed to step 1:
When dividing 5 by 704, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 704

Step 2:
When dividing 52 by 704, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 704

On to step 3:
The number 704 fits into 524 0 times, leaving a remainder of 524.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 524, we end up with 524.
Grab the next digit (5) from the dividend, add it to 524, then carry on: 5245 / 704

On to step 4:
If we divide 5245 by 704, we get 7 and a remainder of 317.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 4928 from 5245 to get 317.
Fetch the next digit (1) from the dividend, attach it to 317 and continue: 3171 / 704

On to step 5:
If we divide 3171 by 704, we get 4 and a remainder of 355.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtracting 2816 from 3171 leaves us with 355.
Bring next digit (8) of the dividend behind the 355 and repeat the process: 3558 / 704

On to step 6:
704 goes into 3558 5 times with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 745.0
Deduct 3520 from 3558 and we're left with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 704

Moving on to step 7:
If we divide 381 by 704, we get 0 and a remainder of 381.
Use 0 as the next digit of our solution. 
Result so far: 7450.0
If we take 0 away from 381, we end up with 381.
Take the next digit (5) from the dividend and append it to 381, then repeat: 3815 / 704

Advancing to step 8:
704 goes into 3815 5 times with a remainder of 295.
Write down 5 as next digit of the result. 
Result so far: 74505.0
The remainder is 295 after subtracting 3520 from 3815.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 9:
The number 704 fits into 2950 4 times, leaving a remainder of 134.
The next digit of our result is 4. 
Result so far: 74505.4
Deduct 2816 from 2950 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 10:
704 can be fit into 1340 1 times, resulting in a remainder of 636.
Put 1 as the next digit of the answer. 
Result so far: 74505.41
If we subtract 704 from 1340, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 11:
When dividing 6360 by 704, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 74505.419
Deduct 6336 from 6360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
704 can be fit into 240 0 times, resulting in a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 74505.419
Deduct 0 from 240 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
If we divide 2400 by 704, we get 3 and a remainder of 288.
Write down 3 as next digit of the result. 
Result so far: 74505.41903
Deduct 2112 from 2400 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
704 can be fit into 2880 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 74505.419034
Subtracting 2816 from 2880 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.

On to step 15:
The number 704 fits into 640 0 times, leaving a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 74505.419034
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 16:
704 goes into 6400 9 times with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 74505.41903409
If we take 6336 away from 6400, we end up 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.

The quotient of the division is 74505.41903409, and the remainder is 6.4e-08.
