897516 ÷ 51 
The aim is to understand the frequency of 51 in 897516.

Going ahead to step 1:
If we divide 8 by 51, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 51

Advancing to step 2:
When dividing 89 by 51, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 89, we end up with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 51

On to step 3:
When dividing 387 by 51, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 357 from 387, we get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 51

On to step 4:
51 goes into 305 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Deduct 255 from 305 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 51

Advancing to step 5:
If we divide 501 by 51, we get 9 and a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 1759.0
Subtracting 459 from 501 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 51

Step 6:
51 goes into 426 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 17598.0
Deduct 408 from 426 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 17598.3
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
51 can be fit into 270 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 17598.35
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 51, we get 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 17598.352
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
If we divide 480 by 51, we get 9 and a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 17598.3529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
51 can be fit into 210 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 17598.35294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
The number 51 fits into 60 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 17598.352941
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 13:
90 divided by 51 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 17598.3529411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 17598.3529411 and a remainder of 3.9e-07.
