77568879 divided by 354 
Our goal is to divide 77568879 by 354.

Going ahead to step 1:
The number 354 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 354

Moving on to step 2:
354 goes into 77 0 times with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 354

Advancing to step 3:
When dividing 775 by 354, we get 2 with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 67 after subtracting 708 from 775.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 354

Advancing to step 4:
354 can be fit into 676 1 times, resulting in a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 354 from 676 leaves us with 322.
Append the next digit (8) from the dividend to 322 and continue with: 3228 / 354

On to step 5:
354 goes into 3228 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 219.0
Subtract 3186 from 3228 to get 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 354

Step 6:
If we divide 428 by 354, we get 1 and a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 2191.0
If we subtract 354 from 428, we get 74.
Include the next digit (7) from the dividend after 74, then repeat: 747 / 354

On to step 7:
The number 354 fits into 747 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 21912.0
Subtract 708 from 747 to get 39.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 354

Advancing to step 8:
354 goes into 399 1 times with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 219121.0
If we take 354 away from 399, 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.

Going ahead to step 9:
If we divide 450 by 354, we get 1 and a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 219121.1
The remainder is 96 after subtracting 354 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
The number 354 fits into 960 2 times, leaving a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 219121.12
If we take 708 away from 960, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 11:
The number 354 fits into 2520 7 times, leaving a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 219121.127
Subtract 2478 from 2520 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
If we divide 420 by 354, we get 1 and a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 219121.1271
Deduct 354 from 420 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
If we divide 660 by 354, we get 1 and a remainder of 306.
The number 1 becomes the next digit in our result. 
Result so far: 219121.12711
Subtracting 354 from 660 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The quotient of the division is 219121.12711, and the remainder is 0.000306.
