68715025 ÷ 51 
Let's see how many times 51 fits into 68715025.

Moving on to step 1:
51 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 51

Moving on to step 2:
68 divided by 51 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 51 from 68 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 51

On to step 3:
51 can be fit into 177 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 153 from 177 to get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 51

Advancing to step 4:
51 goes into 241 4 times with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we take 204 away from 241, we end up with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 51

Let's proceed to step 5:
If we divide 375 by 51, we get 7 and a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 1347.0
If we take 357 away from 375, we end up with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 51

On to step 6:
When dividing 180 by 51, we get 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 13473.0
If we subtract 153 from 180, we get 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 51

Advancing to step 7:
When dividing 272 by 51, we get 5 with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 134735.0
Subtracting 255 from 272 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 51

Advancing to step 8:
When dividing 175 by 51, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 1347353.0
Subtracting 153 from 175 leaves us 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.

Step 9:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1347353.4
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 51, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1347353.43
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
If we divide 70 by 51, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1347353.431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
If we divide 190 by 51, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 1347353.4313
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
If we divide 370 by 51, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1347353.43137
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.

Step 14:
51 can be fit into 130 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 1347353.431372
Deduct 102 from 130 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 15:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1347353.4313725
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 16:
If we divide 250 by 51, we get 4 and a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 1347353.43137254
Deduct 204 from 250 and we're left 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.

The final result is 1347353.43137254 with a remainder of 4.6e-08.
