We're dividing 51017751 by 207 
We want to figure out the number of times 51017751 can be divided by 207.

Advancing to step 1:
If we divide 5 by 207, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 207

Going ahead to step 2:
51 divided by 207 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 207

Going ahead to step 3:
207 goes into 510 2 times with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 414 from 510 leaves us with 96.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 207

Moving on to step 4:
207 goes into 961 4 times with a remainder of 133.
The next digit of our result is 4. 
Result so far: 24.0
Subtracting 828 from 961 leaves us with 133.
Fetch the next digit (7) from the dividend, attach it to 133 and continue: 1337 / 207

Advancing to step 5:
The number 207 fits into 1337 6 times, leaving a remainder of 95.
Put 6 as the next digit of the answer. 
Result so far: 246.0
If we take 1242 away from 1337, we end up with 95.
Fetch the next digit (7) from the dividend, attach it to 95 and continue: 957 / 207

Step 6:
The number 207 fits into 957 4 times, leaving a remainder of 129.
Write down 4 as next digit of the result. 
Result so far: 2464.0
If we take 828 away from 957, we end up with 129.
Grab the next digit (5) from the dividend, add it to 129, then carry on: 1295 / 207

Step 7:
207 can be fit into 1295 6 times, resulting in a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 24646.0
If we subtract 1242 from 1295, we get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 207

On to step 8:
531 divided by 207 is 2 with a remainder of 117.
The next digit of our result is 2. 
Result so far: 246462.0
If we take 414 away from 531, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 9:
When dividing 1170 by 207, we get 5 with a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 246462.5
Subtracting 1035 from 1170 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
1350 divided by 207 is 6 with a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 246462.56
Subtract 1242 from 1350 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
1080 divided by 207 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 246462.565
If we subtract 1035 from 1080, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 12:
If we divide 450 by 207, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 246462.5652
Deduct 414 from 450 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 207 fits into 360 1 times, leaving a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 246462.56521
Deduct 207 from 360 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 14:
207 goes into 1530 7 times with a remainder of 81.
The number 7 becomes the next digit in our result. 
Result so far: 246462.565217
If we subtract 1449 from 1530, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 15:
If we divide 810 by 207, we get 3 and a remainder of 189.
The next digit of our result is 3. 
Result so far: 246462.5652173
If we take 621 away from 810, we end up with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 16:
The number 207 fits into 1890 9 times, leaving a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 246462.56521739
If we subtract 1863 from 1890, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 246462.56521739 with a balance of 2.7e-08.
