357385 ÷ 51 
The aim is to understand the frequency of 51 in 357385.

Advancing to step 1:
The number 51 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 51

Moving on to step 2:
51 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 51

Step 3:
The number 51 fits into 357 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 357 away from 357, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 51

Advancing to step 4:
51 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 51

Going ahead to step 5:
51 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 700.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 51

Step 6:
When dividing 385 by 51, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 7007.0
The remainder is 28 after subtracting 357 from 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 51, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7007.5
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 7007.54
Subtracting 204 from 250 leaves us 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 9:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 7007.549
Deduct 459 from 460 and we're left 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.

Going ahead to step 10:
If we divide 10 by 51, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7007.549
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 7007.54901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
If we divide 490 by 51, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 7007.549019
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.

Step 13:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 7007.5490196
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.

Step 14:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7007.5490196
Deduct 0 from 40 and we're left 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.

The quotient of the division is 7007.5490196, and the remainder is 4e-08.
