68253560 ÷ 430 
We want to figure out the number of times 68253560 can be divided by 430.

On to step 1:
430 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 430

On to step 2:
When dividing 68 by 430, we get 0 with a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Take the next digit (2) from the dividend and append it to 68, then repeat: 682 / 430

On to step 3:
If we divide 682 by 430, we get 1 and a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 430 from 682, we get 252.
Include the next digit (5) from the dividend after 252, then repeat: 2525 / 430

Let's proceed to step 4:
When dividing 2525 by 430, we get 5 with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 2150 from 2525 leaves us with 375.
Bring next digit (3) of the dividend behind the 375 and repeat the process: 3753 / 430

Let's proceed to step 5:
When dividing 3753 by 430, we get 8 with a remainder of 313.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we subtract 3440 from 3753, we get 313.
Grab the next digit (5) from the dividend, add it to 313, then carry on: 3135 / 430

Let's proceed to step 6:
When dividing 3135 by 430, we get 7 with a remainder of 125.
Write down 7 as next digit of the result. 
Result so far: 1587.0
Subtracting 3010 from 3135 leaves us with 125.
Include the next digit (6) from the dividend after 125, then repeat: 1256 / 430

Advancing to step 7:
430 goes into 1256 2 times with a remainder of 396.
The number 2 becomes the next digit in our result. 
Result so far: 15872.0
Subtracting 860 from 1256 leaves us with 396.
Take the next digit (0) from the dividend and append it to 396, then repeat: 3960 / 430

Moving on to step 8:
When dividing 3960 by 430, we get 9 with a remainder of 90.
Write down 9 as next digit of the result. 
Result so far: 158729.0
Subtracting 3870 from 3960 leaves us 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.

On to step 9:
900 divided by 430 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 158729.2
Subtract 860 from 900 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 430, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 158729.2
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
4000 divided by 430 is 9 with a remainder of 130.
Record the quotient 9 as the next digit in the result. 
Result so far: 158729.209
Subtract 3870 from 4000 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 12:
430 goes into 1300 3 times with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 158729.2093
The remainder is 10 after subtracting 1290 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
The number 430 fits into 100 0 times, leaving a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 158729.2093
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 14:
The number 430 fits into 1000 2 times, leaving a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 158729.209302
Subtract 860 from 1000 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
430 goes into 1400 3 times with a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 158729.2093023
The remainder is 110 after subtracting 1290 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 16:
430 can be fit into 1100 2 times, resulting in a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 158729.20930232
Subtract 860 from 1100 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 158729.20930232 and a remainder of 2.4e-07.
