We look at the division of 29867151 by 420 
We want to figure out the number of times 29867151 can be divided by 420.

Step 1:
2 divided by 420 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 420

Step 2:
The number 420 fits into 29 0 times, leaving a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 420

On to step 3:
The number 420 fits into 298 0 times, leaving a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 298 leaves us with 298.
Fetch the next digit (6) from the dividend, attach it to 298 and continue: 2986 / 420

On to step 4:
When dividing 2986 by 420, we get 7 with a remainder of 46.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 2940 from 2986 leaves us with 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 420

Let's proceed to step 5:
If we divide 467 by 420, we get 1 and a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 420 from 467, we get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 420

Step 6:
If we divide 471 by 420, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 711.0
Deduct 420 from 471 and we're left with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 420

Moving on to step 7:
When dividing 515 by 420, we get 1 with a remainder of 95.
The next digit of our result is 1. 
Result so far: 7111.0
The remainder is 95 after subtracting 420 from 515.
Bring next digit (1) of the dividend behind the 95 and repeat the process: 951 / 420

Step 8:
If we divide 951 by 420, we get 2 and a remainder of 111.
Write down 2 as next digit of the result. 
Result so far: 71112.0
If we take 840 away from 951, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 9:
420 can be fit into 1110 2 times, resulting in a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 71112.2
If we subtract 840 from 1110, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
The number 420 fits into 2700 6 times, leaving a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 71112.26
Deduct 2520 from 2700 and we're left 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 11:
1800 divided by 420 is 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 71112.264
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 12:
The number 420 fits into 1200 2 times, leaving a remainder of 360.
The next digit of our result is 2. 
Result so far: 71112.2642
The remainder is 360 after subtracting 840 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
When dividing 3600 by 420, we get 8 with a remainder of 240.
The number 8 becomes the next digit in our result. 
Result so far: 71112.26428
Subtracting 3360 from 3600 leaves us 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 14:
The number 420 fits into 2400 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 71112.264285
Deduct 2100 from 2400 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 15:
The number 420 fits into 3000 7 times, leaving a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 71112.2642857
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.

Advancing to step 16:
600 divided by 420 is 1 with a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 71112.26428571
If we subtract 420 from 600, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 71112.26428571 and a remainder of 1.8e-07.
