Let's divide 391153 by 77
Our goal is to divide 391153 by 77.

Going ahead to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 77

Let's proceed to step 2:
The number 77 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 77

Let's proceed to step 3:
391 divided by 77 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 6 after subtracting 385 from 391.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 77

On to step 4:
When dividing 61 by 77, we get 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Deduct 0 from 61 and we're left with 61.
Include the next digit (5) from the dividend after 61, then repeat: 615 / 77

Moving on to step 5:
When dividing 615 by 77, we get 7 with a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 507.0
If we take 539 away from 615, we end up with 76.
Grab the next digit (3) from the dividend, add it to 76, then carry on: 763 / 77

Step 6:
77 can be fit into 763 9 times, resulting in a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 5079.0
If we subtract 693 from 763, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 5079.9
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
77 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 5079.9
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
When dividing 700 by 77, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 5079.909
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
77 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 5079.909
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
The number 77 fits into 700 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 5079.90909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
When dividing 70 by 77, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 5079.90909
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
If we divide 700 by 77, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 5079.9090909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
77 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 5079.9090909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 5079.9090909 with a remainder of 7e-08.
