We're dividing 50309303 by 678 
We want to figure out the number of times 50309303 can be divided by 678.

Advancing to step 1:
678 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 678

Advancing to step 2:
678 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 678

Going ahead to step 3:
678 can be fit into 503 0 times, resulting in a remainder of 503.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 503 after subtracting 0 from 503.
Append the next digit (0) from the dividend to 503 and continue with: 5030 / 678

Going ahead to step 4:
5030 divided by 678 is 7 with a remainder of 284.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 4746 from 5030 leaves us with 284.
Grab the next digit (9) from the dividend, add it to 284, then carry on: 2849 / 678

Advancing to step 5:
678 goes into 2849 4 times with a remainder of 137.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 2712 away from 2849, we end up with 137.
Fetch the next digit (3) from the dividend, attach it to 137 and continue: 1373 / 678

Going ahead to step 6:
678 can be fit into 1373 2 times, resulting in a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 742.0
Subtract 1356 from 1373 to get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 678

Advancing to step 7:
678 can be fit into 170 0 times, resulting in a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 7420.0
Subtract 0 from 170 to get 170.
Append the next digit (3) from the dividend to 170 and continue with: 1703 / 678

Moving on to step 8:
1703 divided by 678 is 2 with a remainder of 347.
Use 2 as the next digit of our solution. 
Result so far: 74202.0
Deduct 1356 from 1703 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 9:
If we divide 3470 by 678, we get 5 and a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 74202.5
Subtracting 3390 from 3470 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
678 can be fit into 800 1 times, resulting in a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 74202.51
If we take 678 away from 800, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 11:
If we divide 1220 by 678, we get 1 and a remainder of 542.
Use 1 as the next digit of our solution. 
Result so far: 74202.511
If we take 678 away from 1220, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

After the division, we end up with 74202.511 and a remainder of 0.0542.
