15950490 ÷ 51 
We want to divide 15950490 by 51.

Let's proceed to step 1:
51 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 51

On to step 2:
If we divide 15 by 51, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 51

Going ahead to step 3:
159 divided by 51 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 153 away from 159, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 51

Advancing to step 4:
65 divided by 51 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 51 from 65, we get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 51

Step 5:
51 goes into 140 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 312.0
Subtracting 102 from 140 leaves us with 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 51

Advancing to step 6:
The number 51 fits into 384 7 times, leaving a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 3127.0
If we take 357 away from 384, we end up with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 51

Let's proceed to step 7:
279 divided by 51 is 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 31275.0
Deduct 255 from 279 and we're left with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 51

Moving on to step 8:
When dividing 240 by 51, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 312754.0
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
When dividing 360 by 51, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 312754.7
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
If we divide 30 by 51, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 312754.7
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
When dividing 300 by 51, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 312754.705
Deduct 255 from 300 and we're left with 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 51, we get 8 and a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 312754.7058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 312754.70588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 312754.70588 and a remainder of 1.2e-05.
