778661 ÷ 49 
We want to divide 778661 by 49.

On to step 1:
The number 49 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 49

Let's proceed to step 2:
49 goes into 77 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 49 from 77 to get 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 49

On to step 3:
When dividing 288 by 49, we get 5 with a remainder of 43.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 245 from 288 and we're left with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 49

Moving on to step 4:
49 goes into 436 8 times with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtract 392 from 436 to get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 49

Advancing to step 5:
If we divide 446 by 49, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1589.0
Subtract 441 from 446 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 49

Step 6:
When dividing 51 by 49, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 15891.0
If we subtract 49 from 51, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
49 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15891.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 49, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 15891.04
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 49, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15891.04
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 49 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 15891.0408
If we take 392 away from 400, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
When dividing 80 by 49, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 15891.04081
If we take 49 away from 80, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 12:
49 can be fit into 310 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 15891.040816
The remainder is 16 after subtracting 294 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
49 can be fit into 160 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 15891.0408163
If we take 147 away from 160, we end up 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.

Going ahead to step 14:
When dividing 130 by 49, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 15891.04081632
Deduct 98 from 130 and we're left 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.

The final result is 15891.04081632 with a remainder of 3.2e-08.
