78889743 ÷ 277 
Our goal is to divide 78889743 by 277.

Advancing to step 1:
If we divide 7 by 277, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 277

On to step 2:
If we divide 78 by 277, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 277

Advancing to step 3:
The number 277 fits into 788 2 times, leaving a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 554 from 788 leaves us with 234.
Append the next digit (8) from the dividend to 234 and continue with: 2348 / 277

Let's proceed to step 4:
277 can be fit into 2348 8 times, resulting in a remainder of 132.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 2216 away from 2348, we end up with 132.
Append the next digit (9) from the dividend to 132 and continue with: 1329 / 277

On to step 5:
When dividing 1329 by 277, we get 4 with a remainder of 221.
The number 4 becomes the next digit in our result. 
Result so far: 284.0
The remainder is 221 after subtracting 1108 from 1329.
Grab the next digit (7) from the dividend, add it to 221, then carry on: 2217 / 277

On to step 6:
277 goes into 2217 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 2848.0
Subtracting 2216 from 2217 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 277

On to step 7:
If we divide 14 by 277, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 28480.0
If we take 0 away from 14, we end up with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 277

Let's proceed to step 8:
If we divide 143 by 277, we get 0 and a remainder of 143.
Write down 0 as next digit of the result. 
Result so far: 284800.0
If we take 0 away from 143, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 9:
When dividing 1430 by 277, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 284800.5
Subtracting 1385 from 1430 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
450 divided by 277 is 1 with a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 284800.51
If we subtract 277 from 450, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 11:
The number 277 fits into 1730 6 times, leaving a remainder of 68.
The next digit of our result is 6. 
Result so far: 284800.516
If we subtract 1662 from 1730, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 12:
680 divided by 277 is 2 with a remainder of 126.
Put 2 as the next digit of the answer. 
Result so far: 284800.5162
The remainder is 126 after subtracting 554 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 13:
If we divide 1260 by 277, we get 4 and a remainder of 152.
The next digit of our result is 4. 
Result so far: 284800.51624
Deduct 1108 from 1260 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
1520 divided by 277 is 5 with a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 284800.516245
If we take 1385 away from 1520, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 15:
1350 divided by 277 is 4 with a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 284800.5162454
Subtract 1108 from 1350 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 16:
277 can be fit into 2420 8 times, resulting in a remainder of 204.
The next digit of our result is 8. 
Result so far: 284800.51624548
Subtract 2216 from 2420 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

After the division, we end up with 284800.51624548 and a remainder of 2.04e-07.
