15801365 divided by 51 
Our goal is to divide 15801365 by 51.

Let's proceed to step 1:
1 divided by 51 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 51

Step 2:
51 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 51

On to step 3:
When dividing 158 by 51, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
If we take 153 away from 158, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 51

On to step 4:
50 divided by 51 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 50 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 51

Step 5:
When dividing 501 by 51, we get 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
Subtracting 459 from 501 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 51

Going ahead to step 6:
If we divide 423 by 51, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 3098.0
Subtracting 408 from 423 leaves us with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 51

Advancing to step 7:
156 divided by 51 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 30983.0
Subtracting 153 from 156 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 51

Let's proceed to step 8:
51 goes into 35 0 times with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 309830.0
Deduct 0 from 35 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.

Let's proceed to step 9:
If we divide 350 by 51, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 309830.6
If we take 306 away from 350, we end up with 44.
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:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 309830.68
If we take 408 away from 440, we end up 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.

Moving on to step 11:
If we divide 320 by 51, we get 6 and a remainder of 14.
The next digit of our result is 6. 
Result so far: 309830.686
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.

On to step 12:
The number 51 fits into 140 2 times, leaving a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 309830.6862
If we subtract 102 from 140, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
If we divide 380 by 51, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 309830.68627
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.

Going ahead to step 14:
51 goes into 230 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 309830.686274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 15:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 309830.6862745
Deduct 255 from 260 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
If we divide 50 by 51, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 309830.6862745
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 309830.6862745 with a remaining 5e-08.
