Let's divide 71212221 by 430
We want to figure out the number of times 71212221 can be divided by 430.

Moving on to step 1:
When dividing 7 by 430, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 430

Going ahead to step 2:
430 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 430

Going ahead to step 3:
When dividing 712 by 430, we get 1 with a remainder of 282.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 430 from 712, we get 282.
Grab the next digit (1) from the dividend, add it to 282, then carry on: 2821 / 430

Going ahead to step 4:
2821 divided by 430 is 6 with a remainder of 241.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2580 from 2821, we get 241.
Grab the next digit (2) from the dividend, add it to 241, then carry on: 2412 / 430

On to step 5:
430 goes into 2412 5 times with a remainder of 262.
Write down 5 as next digit of the result. 
Result so far: 165.0
The remainder is 262 after subtracting 2150 from 2412.
Take the next digit (2) from the dividend and append it to 262, then repeat: 2622 / 430

Let's proceed to step 6:
When dividing 2622 by 430, we get 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 1656.0
Deduct 2580 from 2622 and we're left with 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 430

Moving on to step 7:
430 can be fit into 422 0 times, resulting in a remainder of 422.
Use 0 as the next digit of our solution. 
Result so far: 16560.0
If we take 0 away from 422, we end up with 422.
Append the next digit (1) from the dividend to 422 and continue with: 4221 / 430

Advancing to step 8:
When dividing 4221 by 430, we get 9 with a remainder of 351.
The number 9 becomes the next digit in our result. 
Result so far: 165609.0
Deduct 3870 from 4221 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Advancing to step 9:
If we divide 3510 by 430, we get 8 and a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 165609.8
Subtract 3440 from 3510 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
When dividing 700 by 430, we get 1 with a remainder of 270.
Record the quotient 1 as the next digit in the result. 
Result so far: 165609.81
The remainder is 270 after subtracting 430 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
If we divide 2700 by 430, we get 6 and a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 165609.816
If we subtract 2580 from 2700, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
When dividing 1200 by 430, we get 2 with a remainder of 340.
Put 2 as the next digit of the answer. 
Result so far: 165609.8162
If we take 860 away from 1200, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
3400 divided by 430 is 7 with a remainder of 390.
Put 7 as the next digit of the answer. 
Result so far: 165609.81627
Subtracting 3010 from 3400 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 14:
When dividing 3900 by 430, we get 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 165609.816279
If we subtract 3870 from 3900, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
When dividing 300 by 430, we get 0 with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 165609.816279
Deduct 0 from 300 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.

Let's proceed to step 16:
3000 divided by 430 is 6 with a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 165609.81627906
Subtracting 2580 from 3000 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 165609.81627906 with a balance of 4.2e-07.
