78763378 ÷ 49 
We're looking to find how many times 49 goes into 78763378.

Step 1:
If we divide 7 by 49, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 49

Going ahead to step 2:
49 goes into 78 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 49 from 78 to get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 49

Moving on to step 3:
49 goes into 297 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 3 after subtracting 294 from 297.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 49

On to step 4:
49 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we take 0 away from 36, we end up with 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 49

Step 5:
49 can be fit into 363 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 1607.0
If we take 343 away from 363, we end up with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 49

Going ahead to step 6:
203 divided by 49 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 16074.0
If we take 196 away from 203, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 49

Moving on to step 7:
The number 49 fits into 77 1 times, leaving a remainder of 28.
The next digit of our result is 1. 
Result so far: 160741.0
Deduct 49 from 77 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 49

Advancing to step 8:
The number 49 fits into 288 5 times, leaving a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 1607415.0
If we subtract 245 from 288, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
49 can be fit into 430 8 times, resulting in a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 1607415.8
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
If we divide 380 by 49, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 1607415.87
Subtract 343 from 380 to 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.

On to step 11:
The number 49 fits into 370 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 1607415.877
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 1607415.877, with a leftover of 0.0027.
