We're dividing 784885 by 51 
The aim is to understand the frequency of 51 in 784885.

Step 1:
7 divided by 51 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 51

Let's proceed to step 2:
If we divide 78 by 51, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 78 and we're left with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 51

Going ahead to step 3:
51 can be fit into 274 5 times, resulting in a remainder of 19.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 19 after subtracting 255 from 274.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 51

Going ahead to step 4:
The number 51 fits into 198 3 times, leaving a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 153.0
The remainder is 45 after subtracting 153 from 198.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 51

Moving on to step 5:
The number 51 fits into 458 8 times, leaving a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 1538.0
If we take 408 away from 458, we end up with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 51

On to step 6:
The number 51 fits into 505 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 15389.0
The remainder is 46 after subtracting 459 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 7:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 15389.9
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 51, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15389.9
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 9:
When dividing 100 by 51, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 15389.901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 10:
When dividing 490 by 51, we get 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 15389.9019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
51 can be fit into 310 6 times, resulting in a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 15389.90196
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
51 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 15389.90196
If we take 0 away from 40, we end up 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.

Let's proceed to step 13:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 15389.9019607
Deduct 357 from 400 and we're left 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.

Advancing to step 14:
If we divide 430 by 51, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 15389.90196078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 15389.90196078, and the remainder is 2.2e-08.
