We're dividing 78429006 by 354 
We want to divide 78429006 by 354.

Advancing to step 1:
If we divide 7 by 354, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 354

Going ahead to step 2:
The number 354 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 354

Advancing to step 3:
If we divide 784 by 354, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 76 after subtracting 708 from 784.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 354

Let's proceed to step 4:
762 divided by 354 is 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 708 from 762, we get 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 354

Let's proceed to step 5:
354 goes into 549 1 times with a remainder of 195.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtracting 354 from 549 leaves us with 195.
Append the next digit (0) from the dividend to 195 and continue with: 1950 / 354

Advancing to step 6:
The number 354 fits into 1950 5 times, leaving a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 2215.0
If we take 1770 away from 1950, we end up with 180.
Append the next digit (0) from the dividend to 180 and continue with: 1800 / 354

Going ahead to step 7:
354 can be fit into 1800 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 22155.0
If we subtract 1770 from 1800, we get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 354

Going ahead to step 8:
When dividing 306 by 354, we get 0 with a remainder of 306.
Put 0 as the next digit of the answer. 
Result so far: 221550.0
If we take 0 away from 306, we end up 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.

On to step 9:
354 can be fit into 3060 8 times, resulting in a remainder of 228.
The next digit of our result is 8. 
Result so far: 221550.8
If we take 2832 away from 3060, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
If we divide 2280 by 354, we get 6 and a remainder of 156.
The next digit of our result is 6. 
Result so far: 221550.86
Subtracting 2124 from 2280 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 11:
If we divide 1560 by 354, we get 4 and a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 221550.864
If we take 1416 away from 1560, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
354 can be fit into 1440 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 221550.8644
Subtracting 1416 from 1440 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 221550.8644 and a remainder of 0.00024.
