We're dividing 3137620 by 672 
The aim is to understand the frequency of 672 in 3137620.

On to step 1:
672 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 672

Moving on to step 2:
The number 672 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 672

On to step 3:
If we divide 313 by 672, we get 0 and a remainder of 313.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 313 after subtracting 0 from 313.
Bring next digit (7) of the dividend behind the 313 and repeat the process: 3137 / 672

Going ahead to step 4:
672 goes into 3137 4 times with a remainder of 449.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2688 from 3137, we get 449.
Take the next digit (6) from the dividend and append it to 449, then repeat: 4496 / 672

Moving on to step 5:
672 can be fit into 4496 6 times, resulting in a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 4032 from 4496 and we're left with 464.
Take the next digit (2) from the dividend and append it to 464, then repeat: 4642 / 672

Going ahead to step 6:
672 can be fit into 4642 6 times, resulting in a remainder of 610.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
Subtracting 4032 from 4642 leaves us with 610.
Grab the next digit (0) from the dividend, add it to 610, then carry on: 6100 / 672

Step 7:
If we divide 6100 by 672, we get 9 and a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 4669.0
Deduct 6048 from 6100 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
672 can be fit into 520 0 times, resulting in a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 4669.0
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 9:
If we divide 5200 by 672, we get 7 and a remainder of 496.
Put 7 as the next digit of the answer. 
Result so far: 4669.07
If we take 4704 away from 5200, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 10:
If we divide 4960 by 672, we get 7 and a remainder of 256.
Use 7 as the next digit of our solution. 
Result so far: 4669.077
Subtract 4704 from 4960 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 4669.077 with a remaining 0.0256.
