557412 divided by 77 
Our goal is to divide 557412 by 77.

Step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 77

On to step 2:
55 divided by 77 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 77

Step 3:
The number 77 fits into 557 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 539 from 557, we get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 77

Moving on to step 4:
When dividing 184 by 77, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 154 from 184 and we're left with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 77

Step 5:
The number 77 fits into 301 3 times, leaving a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 723.0
Deduct 231 from 301 and we're left with 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 77

Moving on to step 6:
702 divided by 77 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 7239.0
Subtracting 693 from 702 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 77 fits into 90 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 7239.1
Deduct 77 from 90 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
When dividing 130 by 77, we get 1 with a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 7239.11
Subtracting 77 from 130 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 7239.11 with a remaining 0.053.
