29829123 divided by 420 
Our goal is to divide 29829123 by 420.

Step 1:
If we divide 2 by 420, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 420

Going ahead to step 2:
420 goes into 29 0 times with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 420

On to step 3:
298 divided by 420 is 0 with a remainder of 298.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 298 and we're left with 298.
Bring next digit (2) of the dividend behind the 298 and repeat the process: 2982 / 420

Advancing to step 4:
The number 420 fits into 2982 7 times, leaving a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 42 after subtracting 2940 from 2982.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 420

Advancing to step 5:
429 divided by 420 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 420 away from 429, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 420

Step 6:
If we divide 91 by 420, we get 0 and a remainder of 91.
The next digit of our result is 0. 
Result so far: 710.0
Subtracting 0 from 91 leaves us with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 420

Going ahead to step 7:
420 goes into 912 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 7102.0
If we take 840 away from 912, we end up with 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 420

Advancing to step 8:
723 divided by 420 is 1 with a remainder of 303.
The number 1 becomes the next digit in our result. 
Result so far: 71021.0
Subtract 420 from 723 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

On to step 9:
3030 divided by 420 is 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 71021.7
If we subtract 2940 from 3030, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
420 can be fit into 900 2 times, resulting in a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 71021.72
Subtracting 840 from 900 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
The number 420 fits into 600 1 times, leaving a remainder of 180.
The next digit of our result is 1. 
Result so far: 71021.721
If we take 420 away from 600, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
If we divide 1800 by 420, we get 4 and a remainder of 120.
Use 4 as the next digit of our solution. 
Result so far: 71021.7214
If we take 1680 away from 1800, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
1200 divided by 420 is 2 with a remainder of 360.
The next digit of our result is 2. 
Result so far: 71021.72142
If we take 840 away from 1200, we end up 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.

Step 14:
The number 420 fits into 3600 8 times, leaving a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 71021.721428
If we take 3360 away from 3600, we end up with 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 15:
420 goes into 2400 5 times with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 71021.7214285
If we take 2100 away from 2400, we end up 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:
420 goes into 3000 7 times with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 71021.72142857
The remainder is 60 after subtracting 2940 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 71021.72142857 and a remainder of 6e-08.
