99928729 ÷ 470 
Let's see how many times 470 fits into 99928729.

Advancing to step 1:
470 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 470

Step 2:
470 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 470

Going ahead to step 3:
If we divide 999 by 470, we get 2 and a remainder of 59.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 940 from 999 and we're left with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 470

Step 4:
When dividing 592 by 470, we get 1 with a remainder of 122.
The next digit of our result is 1. 
Result so far: 21.0
If we take 470 away from 592, we end up with 122.
Append the next digit (8) from the dividend to 122 and continue with: 1228 / 470

Let's proceed to step 5:
470 can be fit into 1228 2 times, resulting in a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 940 from 1228 leaves us with 288.
Fetch the next digit (7) from the dividend, attach it to 288 and continue: 2887 / 470

Let's proceed to step 6:
The number 470 fits into 2887 6 times, leaving a remainder of 67.
Record the quotient 6 as the next digit in the result. 
Result so far: 2126.0
Subtract 2820 from 2887 to get 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 470

Step 7:
If we divide 672 by 470, we get 1 and a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 21261.0
Subtract 470 from 672 to get 202.
Bring next digit (9) of the dividend behind the 202 and repeat the process: 2029 / 470

Moving on to step 8:
When dividing 2029 by 470, we get 4 with a remainder of 149.
The number 4 becomes the next digit in our result. 
Result so far: 212614.0
If we take 1880 away from 2029, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 9:
If we divide 1490 by 470, we get 3 and a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 212614.3
Deduct 1410 from 1490 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
470 goes into 800 1 times with a remainder of 330.
The number 1 becomes the next digit in our result. 
Result so far: 212614.31
If we subtract 470 from 800, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 11:
3300 divided by 470 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 212614.317
Deduct 3290 from 3300 and we're left 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 12:
470 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 212614.317
Deduct 0 from 100 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
470 goes into 1000 2 times with a remainder of 60.
The next digit of our result is 2. 
Result so far: 212614.31702
Subtract 940 from 1000 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
600 divided by 470 is 1 with a remainder of 130.
The number 1 becomes the next digit in our result. 
Result so far: 212614.317021
Deduct 470 from 600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 15:
When dividing 1300 by 470, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 212614.3170212
Deduct 940 from 1300 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 16:
If we divide 3600 by 470, we get 7 and a remainder of 310.
Put 7 as the next digit of the answer. 
Result so far: 212614.31702127
Deduct 3290 from 3600 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 212614.31702127 and a remainder of 3.1e-07.
