Let's divide 77872785 by 277
Our goal is to divide 77872785 by 277.

Step 1:
When dividing 7 by 277, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 277

Step 2:
When dividing 77 by 277, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 277

Advancing to step 3:
778 divided by 277 is 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 554 from 778 to get 224.
Fetch the next digit (7) from the dividend, attach it to 224 and continue: 2247 / 277

On to step 4:
The number 277 fits into 2247 8 times, leaving a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 2216 away from 2247, we end up with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 277

Let's proceed to step 5:
277 goes into 312 1 times with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtracting 277 from 312 leaves us with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 277

Step 6:
The number 277 fits into 357 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 2811.0
The remainder is 80 after subtracting 277 from 357.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 277

Going ahead to step 7:
If we divide 808 by 277, we get 2 and a remainder of 254.
Record the quotient 2 as the next digit in the result. 
Result so far: 28112.0
The remainder is 254 after subtracting 554 from 808.
Include the next digit (5) from the dividend after 254, then repeat: 2545 / 277

Going ahead to step 8:
277 goes into 2545 9 times with a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 281129.0
If we subtract 2493 from 2545, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
If we divide 520 by 277, we get 1 and a remainder of 243.
Write down 1 as next digit of the result. 
Result so far: 281129.1
The remainder is 243 after subtracting 277 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 10:
2430 divided by 277 is 8 with a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 281129.18
If we take 2216 away from 2430, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
277 can be fit into 2140 7 times, resulting in a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 281129.187
If we take 1939 away from 2140, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 12:
If we divide 2010 by 277, we get 7 and a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 281129.1877
Subtract 1939 from 2010 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.

The final outcome is 281129.1877, with a leftover of 0.00071.
