We look at the division of 29908642 by 420 
We're looking to find how many times 420 goes into 29908642.

Step 1:
420 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 420

Let's proceed to step 2:
The number 420 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 420

Advancing to step 3:
420 can be fit into 299 0 times, resulting in a remainder of 299.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 299 and we're left with 299.
Include the next digit (0) from the dividend after 299, then repeat: 2990 / 420

Let's proceed to step 4:
420 can be fit into 2990 7 times, resulting in a remainder of 50.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 2940 from 2990 leaves us with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 420

Moving on to step 5:
420 can be fit into 508 1 times, resulting in a remainder of 88.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 420 from 508 to get 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 420

Advancing to step 6:
420 goes into 886 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 712.0
Subtract 840 from 886 to get 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 420

Let's proceed to step 7:
The number 420 fits into 464 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 7121.0
If we take 420 away from 464, we end up with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 420

Step 8:
442 divided by 420 is 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 71211.0
Subtract 420 from 442 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
420 can be fit into 220 0 times, resulting in a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 71211.0
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
When dividing 2200 by 420, we get 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 71211.05
Subtracting 2100 from 2200 leaves us 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.

Going ahead to step 11:
If we divide 1000 by 420, we get 2 and a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 71211.052
If we take 840 away from 1000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
420 can be fit into 1600 3 times, resulting in a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 71211.0523
If we subtract 1260 from 1600, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
420 goes into 3400 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 71211.05238
Subtracting 3360 from 3400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
The number 420 fits into 400 0 times, leaving a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 71211.05238
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 15:
420 goes into 4000 9 times with a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 71211.0523809
Deduct 3780 from 4000 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 16:
If we divide 2200 by 420, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 71211.05238095
Subtracting 2100 from 2200 leaves us 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.

In conclusion, the division gives 71211.05238095 with a balance of 1e-07.
