485642 ÷ 77 
We want to divide 485642 by 77.

Advancing to step 1:
When dividing 4 by 77, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 77

Let's proceed to step 2:
When dividing 48 by 77, we get 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (5) of the dividend behind the 48 and repeat the process: 485 / 77

Going ahead to step 3:
77 goes into 485 6 times with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 462 from 485 to get 23.
Bring next digit (6) of the dividend behind the 23 and repeat the process: 236 / 77

Advancing to step 4:
If we divide 236 by 77, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Deduct 231 from 236 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 77

Going ahead to step 5:
The number 77 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 630.0
The remainder is 54 after subtracting 0 from 54.
Grab the next digit (2) from the dividend, add it to 54, then carry on: 542 / 77

Advancing to step 6:
77 goes into 542 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 6307.0
The remainder is 3 after subtracting 539 from 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 77, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6307.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 77 is 3 with a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 6307.03
The remainder is 69 after subtracting 231 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
When dividing 690 by 77, we get 8 with a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 6307.038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 6307.0389
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 11:
77 can be fit into 470 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6307.03896
If we subtract 462 from 470, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
77 can be fit into 80 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 6307.038961
If we subtract 77 from 80, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
If we divide 30 by 77, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 6307.038961
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
If we divide 300 by 77, we get 3 and a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 6307.03896103
Subtract 231 from 300 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

After the division, we end up with 6307.03896103 and a remainder of 6.9e-08.
