We divide 637043 by 51
The aim is to understand the frequency of 51 in 637043.

Advancing to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 51

Step 2:
If we divide 63 by 51, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 51 from 63, we get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 51

Going ahead to step 3:
127 divided by 51 is 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 25 after subtracting 102 from 127.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 51

Moving on to step 4:
If we divide 250 by 51, we get 4 and a remainder of 46.
The next digit of our result is 4. 
Result so far: 124.0
If we take 204 away from 250, we end up with 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 51

On to step 5:
The number 51 fits into 464 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1249.0
Subtracting 459 from 464 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 51

On to step 6:
51 goes into 53 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 12491.0
Deduct 51 from 53 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
If we divide 20 by 51, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12491.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
51 goes into 200 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 12491.03
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
If we divide 470 by 51, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 12491.039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 12491.0392
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 12491.03921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
When dividing 290 by 51, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 12491.039215
Deduct 255 from 290 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
The number 51 fits into 350 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 12491.0392156
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
51 goes into 440 8 times with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 12491.03921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 12491.03921568 with a remaining 3.2e-08.
