68454240 ÷ 355 
We want to divide 68454240 by 355.

Let's proceed to step 1:
If we divide 6 by 355, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 355

Let's proceed to step 2:
68 divided by 355 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 355

On to step 3:
355 can be fit into 684 1 times, resulting in a remainder of 329.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 329 after subtracting 355 from 684.
Grab the next digit (5) from the dividend, add it to 329, then carry on: 3295 / 355

Step 4:
355 goes into 3295 9 times with a remainder of 100.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 3195 from 3295, we get 100.
Take the next digit (4) from the dividend and append it to 100, then repeat: 1004 / 355

Step 5:
1004 divided by 355 is 2 with a remainder of 294.
The next digit of our result is 2. 
Result so far: 192.0
The remainder is 294 after subtracting 710 from 1004.
Bring next digit (2) of the dividend behind the 294 and repeat the process: 2942 / 355

Step 6:
If we divide 2942 by 355, we get 8 and a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 1928.0
If we take 2840 away from 2942, we end up with 102.
Fetch the next digit (4) from the dividend, attach it to 102 and continue: 1024 / 355

Moving on to step 7:
355 can be fit into 1024 2 times, resulting in a remainder of 314.
The number 2 becomes the next digit in our result. 
Result so far: 19282.0
Subtracting 710 from 1024 leaves us with 314.
Take the next digit (0) from the dividend and append it to 314, then repeat: 3140 / 355

Step 8:
355 goes into 3140 8 times with a remainder of 300.
Use 8 as the next digit of our solution. 
Result so far: 192828.0
Deduct 2840 from 3140 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 9:
When dividing 3000 by 355, we get 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 192828.8
Subtract 2840 from 3000 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 10:
355 goes into 1600 4 times with a remainder of 180.
The next digit of our result is 4. 
Result so far: 192828.84
If we take 1420 away from 1600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
The number 355 fits into 1800 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 192828.845
Deduct 1775 from 1800 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
When dividing 250 by 355, we get 0 with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 192828.845
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
355 can be fit into 2500 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 192828.84507
Subtract 2485 from 2500 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
355 can be fit into 150 0 times, resulting in a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 192828.84507
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
1500 divided by 355 is 4 with a remainder of 80.
The next digit of our result is 4. 
Result so far: 192828.8450704
Deduct 1420 from 1500 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 16:
If we divide 800 by 355, we get 2 and a remainder of 90.
Put 2 as the next digit of the answer. 
Result so far: 192828.84507042
If we take 710 away from 800, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Our division results in 192828.84507042 with a remaining 9e-08.
