554639 ÷ 77 
Our goal is to divide 554639 by 77.

On to step 1:
77 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 77

Advancing to step 2:
77 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 77

Step 3:
When dividing 554 by 77, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 539 from 554 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 77

On to step 4:
If we divide 156 by 77, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 154 from 156 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 77

Step 5:
If we divide 23 by 77, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 720.0
If we take 0 away from 23, we end up with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 77

Advancing to step 6:
77 goes into 239 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 7203.0
If we subtract 231 from 239, 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.

Let's proceed to step 7:
The number 77 fits into 80 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7203.1
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.

Let's proceed to step 8:
77 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 7203.1
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 9:
77 can be fit into 300 3 times, resulting in a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 7203.103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
If we divide 690 by 77, we get 8 and a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 7203.1038
If we take 616 away from 690, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
77 goes into 740 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 7203.10389
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
If we divide 470 by 77, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7203.103896
If we take 462 away from 470, we end up with 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 13:
80 divided by 77 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 7203.1038961
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 7203.1038961
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.

The final outcome is 7203.1038961, with a leftover of 3e-08.
