453821 ÷ 77 
Our goal is to divide 453821 by 77.

Advancing to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 77

Going ahead to step 2:
77 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 77

Going ahead to step 3:
77 goes into 453 5 times with a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 385 from 453 and we're left with 68.
Append the next digit (8) from the dividend to 68 and continue with: 688 / 77

Moving on to step 4:
The number 77 fits into 688 8 times, leaving a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Deduct 616 from 688 and we're left with 72.
Append the next digit (2) from the dividend to 72 and continue with: 722 / 77

Step 5:
722 divided by 77 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 589.0
Subtracting 693 from 722 leaves us with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 77

Moving on to step 6:
291 divided by 77 is 3 with a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 5893.0
If we take 231 away from 291, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
600 divided by 77 is 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 5893.7
If we take 539 away from 600, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 8:
When dividing 610 by 77, we get 7 with a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 5893.77
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Our division results in 5893.77 with a remaining 0.071.
