700399 divided by 51 
The aim is to understand the frequency of 51 in 700399.

Step 1:
7 divided by 51 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 51

On to step 2:
51 can be fit into 70 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 70 and we're left with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 51

Let's proceed to step 3:
190 divided by 51 is 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 153 from 190 and we're left with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 51

Going ahead to step 4:
373 divided by 51 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 137.0
Subtract 357 from 373 to get 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 51

Step 5:
If we divide 169 by 51, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1373.0
Subtracting 153 from 169 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 51

Let's proceed to step 6:
The number 51 fits into 169 3 times, leaving a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 13733.0
If we take 153 away from 169, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
51 can be fit into 160 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 13733.3
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
70 divided by 51 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 13733.31
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
51 goes into 190 3 times with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 13733.313
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
51 can be fit into 370 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 13733.3137
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
130 divided by 51 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 13733.31372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
If we divide 280 by 51, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 13733.313725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
51 goes into 250 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 13733.3137254
If we take 204 away from 250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 13733.31372549
Subtracting 459 from 460 leaves us 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.

After the division, we end up with 13733.31372549 and a remainder of 1e-09.
