916529 ÷ 51 
The aim is to understand the frequency of 51 in 916529.

Going ahead to step 1:
51 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 51

On to step 2:
51 goes into 91 1 times with a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 91, we get 40.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 51

Going ahead to step 3:
51 goes into 406 7 times with a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 357 from 406 and we're left with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 51

Let's proceed to step 4:
51 can be fit into 495 9 times, resulting in a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 179.0
If we take 459 away from 495, we end up with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 51

Going ahead to step 5:
When dividing 362 by 51, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1797.0
If we subtract 357 from 362, we get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 51

Advancing to step 6:
The number 51 fits into 59 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 17971.0
Subtracting 51 from 59 leaves us 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.

On to step 7:
If we divide 80 by 51, we get 1 and a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 17971.1
If we take 51 away from 80, we end up 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.

Moving on to step 8:
If we divide 290 by 51, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17971.15
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.

Step 9:
The number 51 fits into 350 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 17971.156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
If we divide 440 by 51, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 17971.1568
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.

Going ahead to step 11:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 17971.15686
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 51, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 17971.156862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
51 goes into 380 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 17971.1568627
Subtracting 357 from 380 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
When dividing 230 by 51, we get 4 with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 17971.15686274
Deduct 204 from 230 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 17971.15686274 with a balance of 2.6e-08.
