78498351 divided by 291 
Our goal is to divide 78498351 by 291.

Step 1:
7 divided by 291 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 291

Advancing to step 2:
The number 291 fits into 78 0 times, leaving a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 291

Let's proceed to step 3:
If we divide 784 by 291, we get 2 and a remainder of 202.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 202 after subtracting 582 from 784.
Fetch the next digit (9) from the dividend, attach it to 202 and continue: 2029 / 291

Step 4:
291 can be fit into 2029 6 times, resulting in a remainder of 283.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 283 after subtracting 1746 from 2029.
Bring next digit (8) of the dividend behind the 283 and repeat the process: 2838 / 291

Step 5:
If we divide 2838 by 291, we get 9 and a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 269.0
Subtracting 2619 from 2838 leaves us with 219.
Append the next digit (3) from the dividend to 219 and continue with: 2193 / 291

Going ahead to step 6:
2193 divided by 291 is 7 with a remainder of 156.
Use 7 as the next digit of our solution. 
Result so far: 2697.0
Subtracting 2037 from 2193 leaves us with 156.
Bring next digit (5) of the dividend behind the 156 and repeat the process: 1565 / 291

Advancing to step 7:
When dividing 1565 by 291, we get 5 with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 26975.0
If we take 1455 away from 1565, we end up with 110.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 291

On to step 8:
If we divide 1101 by 291, we get 3 and a remainder of 228.
Record the quotient 3 as the next digit in the result. 
Result so far: 269753.0
The remainder is 228 after subtracting 873 from 1101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 9:
When dividing 2280 by 291, we get 7 with a remainder of 243.
Write down 7 as next digit of the result. 
Result so far: 269753.7
The remainder is 243 after subtracting 2037 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 10:
2430 divided by 291 is 8 with a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 269753.78
Deduct 2328 from 2430 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 11:
The number 291 fits into 1020 3 times, leaving a remainder of 147.
The next digit of our result is 3. 
Result so far: 269753.783
If we subtract 873 from 1020, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 12:
291 can be fit into 1470 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 269753.7835
If we take 1455 away from 1470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
291 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 269753.7835
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
291 can be fit into 1500 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 269753.783505
If we take 1455 away from 1500, we end up 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.

On to step 15:
450 divided by 291 is 1 with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 269753.7835051
If we take 291 away from 450, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 16:
When dividing 1590 by 291, we get 5 with a remainder of 135.
Record the quotient 5 as the next digit in the result. 
Result so far: 269753.78350515
Deduct 1455 from 1590 and we're left 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.

In conclusion, the division gives 269753.78350515 with a balance of 1.35e-07.
