Let's divide 63078961 by 51
We want to divide 63078961 by 51.

Step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 51

Let's proceed to step 2:
When dividing 63 by 51, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 12 after subtracting 51 from 63.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 51

Going ahead to step 3:
The number 51 fits into 120 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 12.0
If we take 102 away from 120, we end up with 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 51

Step 4:
187 divided by 51 is 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 123.0
Deduct 153 from 187 and we're left with 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 51

Step 5:
51 goes into 348 6 times with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 1236.0
If we subtract 306 from 348, we get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 51

Moving on to step 6:
429 divided by 51 is 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 12368.0
The remainder is 21 after subtracting 408 from 429.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 51

Going ahead to step 7:
If we divide 216 by 51, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 123684.0
Subtracting 204 from 216 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 51

Step 8:
When dividing 121 by 51, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 1236842.0
Subtracting 102 from 121 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
51 goes into 190 3 times with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 1236842.3
If we subtract 153 from 190, we 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.

Moving on to step 10:
51 goes into 370 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1236842.37
The remainder is 13 after subtracting 357 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
130 divided by 51 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1236842.372
Subtracting 102 from 130 leaves us 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.

Step 12:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1236842.3725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 13:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 1236842.37254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
When dividing 460 by 51, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1236842.372549
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 15:
If we divide 10 by 51, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1236842.372549
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 16:
When dividing 100 by 51, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1236842.37254901
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 1236842.37254901 and a remainder of 4.9e-08.
