We're dividing 77349576 by 391 
Our goal is to divide 77349576 by 391.

Going ahead to step 1:
391 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 391

Step 2:
When dividing 77 by 391, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 391

Let's proceed to step 3:
391 goes into 773 1 times with a remainder of 382.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 391 from 773 leaves us with 382.
Bring next digit (4) of the dividend behind the 382 and repeat the process: 3824 / 391

On to step 4:
391 can be fit into 3824 9 times, resulting in a remainder of 305.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 3519 from 3824, we get 305.
Grab the next digit (9) from the dividend, add it to 305, then carry on: 3059 / 391

Moving on to step 5:
If we divide 3059 by 391, we get 7 and a remainder of 322.
Use 7 as the next digit of our solution. 
Result so far: 197.0
If we take 2737 away from 3059, we end up with 322.
Bring next digit (5) of the dividend behind the 322 and repeat the process: 3225 / 391

Going ahead to step 6:
If we divide 3225 by 391, we get 8 and a remainder of 97.
Write down 8 as next digit of the result. 
Result so far: 1978.0
Deduct 3128 from 3225 and we're left with 97.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 391

Moving on to step 7:
When dividing 977 by 391, we get 2 with a remainder of 195.
Record the quotient 2 as the next digit in the result. 
Result so far: 19782.0
Subtract 782 from 977 to get 195.
Grab the next digit (6) from the dividend, add it to 195, then carry on: 1956 / 391

Advancing to step 8:
When dividing 1956 by 391, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 197825.0
Deduct 1955 from 1956 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
The number 391 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 197825.0
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.

Moving on to step 10:
391 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 197825.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 197825.0 with a remaining 0.1.
