We look at the division of 19879930 by 430 
We want to figure out the number of times 19879930 can be divided by 430.

Let's proceed to step 1:
1 divided by 430 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 430

Going ahead to step 2:
19 divided by 430 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 430

Moving on to step 3:
The number 430 fits into 198 0 times, leaving a remainder of 198.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Take the next digit (7) from the dividend and append it to 198, then repeat: 1987 / 430

On to step 4:
The number 430 fits into 1987 4 times, leaving a remainder of 267.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1720 from 1987, we get 267.
Grab the next digit (9) from the dividend, add it to 267, then carry on: 2679 / 430

Moving on to step 5:
2679 divided by 430 is 6 with a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 2580 from 2679 and we're left with 99.
Grab the next digit (9) from the dividend, add it to 99, then carry on: 999 / 430

Advancing to step 6:
430 goes into 999 2 times with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 462.0
Subtract 860 from 999 to get 139.
Take the next digit (3) from the dividend and append it to 139, then repeat: 1393 / 430

Moving on to step 7:
430 goes into 1393 3 times with a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 4623.0
If we subtract 1290 from 1393, we get 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 430

Let's proceed to step 8:
The number 430 fits into 1030 2 times, leaving a remainder of 170.
The next digit of our result is 2. 
Result so far: 46232.0
If we subtract 860 from 1030, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 9:
The number 430 fits into 1700 3 times, leaving a remainder of 410.
Put 3 as the next digit of the answer. 
Result so far: 46232.3
Subtracting 1290 from 1700 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
430 can be fit into 4100 9 times, resulting in a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 46232.39
If we subtract 3870 from 4100, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
If we divide 2300 by 430, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 46232.395
Subtract 2150 from 2300 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
If we divide 1500 by 430, we get 3 and a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 46232.3953
Subtracting 1290 from 1500 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 13:
The number 430 fits into 2100 4 times, leaving a remainder of 380.
Use 4 as the next digit of our solution. 
Result so far: 46232.39534
If we subtract 1720 from 2100, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 14:
430 goes into 3800 8 times with a remainder of 360.
The number 8 becomes the next digit in our result. 
Result so far: 46232.395348
If we subtract 3440 from 3800, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
The number 430 fits into 3600 8 times, leaving a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 46232.3953488
Subtract 3440 from 3600 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.

The final result is 46232.3953488 with a remainder of 1.6e-06.
