We're dividing 694774 by 51 
The aim is to understand the frequency of 51 in 694774.

Advancing to step 1:
6 divided by 51 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 51

Moving on to step 2:
If we divide 69 by 51, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 18 after subtracting 51 from 69.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 51

Moving on to step 3:
184 divided by 51 is 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 153 from 184 and we're left with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 51

On to step 4:
51 goes into 317 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtracting 306 from 317 leaves us with 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 51

Step 5:
The number 51 fits into 117 2 times, leaving a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 1362.0
If we take 102 away from 117, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 51

Moving on to step 6:
If we divide 154 by 51, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 13623.0
If we take 153 away from 154, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13623.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
51 can be fit into 100 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 13623.01
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
490 divided by 51 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 13623.019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
51 goes into 310 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13623.0196
The remainder is 4 after subtracting 306 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
40 divided by 51 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13623.0196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 13623.019607
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
When dividing 430 by 51, we get 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 13623.0196078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
If we divide 220 by 51, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 13623.01960784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 13623.01960784 with a remainder of 1.6e-08.
