Let's divide 72979257 by 430
We want to figure out the number of times 72979257 can be divided by 430.

On to step 1:
The number 430 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 430

Moving on to step 2:
430 can be fit into 72 0 times, resulting in a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 430

On to step 3:
The number 430 fits into 729 1 times, leaving a remainder of 299.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 430 from 729 leaves us with 299.
Include the next digit (7) from the dividend after 299, then repeat: 2997 / 430

Moving on to step 4:
If we divide 2997 by 430, we get 6 and a remainder of 417.
The next digit of our result is 6. 
Result so far: 16.0
Subtracting 2580 from 2997 leaves us with 417.
Bring next digit (9) of the dividend behind the 417 and repeat the process: 4179 / 430

Moving on to step 5:
4179 divided by 430 is 9 with a remainder of 309.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
If we subtract 3870 from 4179, we get 309.
Include the next digit (2) from the dividend after 309, then repeat: 3092 / 430

Step 6:
The number 430 fits into 3092 7 times, leaving a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 1697.0
Deduct 3010 from 3092 and we're left with 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 430

Advancing to step 7:
The number 430 fits into 825 1 times, leaving a remainder of 395.
Record the quotient 1 as the next digit in the result. 
Result so far: 16971.0
Deduct 430 from 825 and we're left with 395.
Include the next digit (7) from the dividend after 395, then repeat: 3957 / 430

Moving on to step 8:
When dividing 3957 by 430, we get 9 with a remainder of 87.
The next digit of our result is 9. 
Result so far: 169719.0
The remainder is 87 after subtracting 3870 from 3957.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 9:
430 goes into 870 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 169719.2
Subtracting 860 from 870 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 430, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 169719.2
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 430, we get 2 with a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 169719.202
If we subtract 860 from 1000, we 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.

On to step 12:
If we divide 1400 by 430, we get 3 and a remainder of 110.
Use 3 as the next digit of our solution. 
Result so far: 169719.2023
If we subtract 1290 from 1400, 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 13:
When dividing 1100 by 430, we get 2 with a remainder of 240.
The next digit of our result is 2. 
Result so far: 169719.20232
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.

On to step 14:
430 goes into 2400 5 times with a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 169719.202325
Deduct 2150 from 2400 and we're left 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.

Moving on to step 15:
If we divide 2500 by 430, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 169719.2023255
Subtract 2150 from 2500 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Our division results in 169719.2023255 with a remaining 3.5e-06.
