68112269 ÷ 430 
We want to divide 68112269 by 430.

On to step 1:
The number 430 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 430

On to step 2:
When dividing 68 by 430, we get 0 with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Fetch the next digit (1) from the dividend, attach it to 68 and continue: 681 / 430

Advancing to step 3:
If we divide 681 by 430, we get 1 and a remainder of 251.
The next digit of our result is 1. 
Result so far: 1.0
If we take 430 away from 681, we end up with 251.
Bring next digit (1) of the dividend behind the 251 and repeat the process: 2511 / 430

Let's proceed to step 4:
When dividing 2511 by 430, we get 5 with a remainder of 361.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2150 from 2511, we get 361.
Grab the next digit (2) from the dividend, add it to 361, then carry on: 3612 / 430

Let's proceed to step 5:
430 can be fit into 3612 8 times, resulting in a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we subtract 3440 from 3612, we get 172.
Include the next digit (2) from the dividend after 172, then repeat: 1722 / 430

Let's proceed to step 6:
The number 430 fits into 1722 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1584.0
Deduct 1720 from 1722 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 430

Step 7:
430 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 15840.0
If we take 0 away from 26, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 430

Advancing to step 8:
269 divided by 430 is 0 with a remainder of 269.
Write down 0 as next digit of the result. 
Result so far: 158400.0
Subtracting 0 from 269 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 9:
If we divide 2690 by 430, we get 6 and a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 158400.6
If we subtract 2580 from 2690, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
1100 divided by 430 is 2 with a remainder of 240.
Put 2 as the next digit of the answer. 
Result so far: 158400.62
Subtracting 860 from 1100 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
430 goes into 2400 5 times with a remainder of 250.
The next digit of our result is 5. 
Result so far: 158400.625
If we take 2150 away from 2400, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 12:
The number 430 fits into 2500 5 times, leaving a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 158400.6255
Deduct 2150 from 2500 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

After the division, we end up with 158400.6255 and a remainder of 0.0035.
