14111512 divided by 420 
Our goal is to divide 14111512 by 420.

Step 1:
420 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 420

Going ahead to step 2:
When dividing 14 by 420, we get 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 420

On to step 3:
When dividing 141 by 420, we get 0 with a remainder of 141.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 141 to get 141.
Include the next digit (1) from the dividend after 141, then repeat: 1411 / 420

Moving on to step 4:
420 can be fit into 1411 3 times, resulting in a remainder of 151.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 1260 from 1411 leaves us with 151.
Take the next digit (1) from the dividend and append it to 151, then repeat: 1511 / 420

Advancing to step 5:
420 goes into 1511 3 times with a remainder of 251.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 1260 away from 1511, we end up with 251.
Bring next digit (5) of the dividend behind the 251 and repeat the process: 2515 / 420

Let's proceed to step 6:
2515 divided by 420 is 5 with a remainder of 415.
Put 5 as the next digit of the answer. 
Result so far: 335.0
Deduct 2100 from 2515 and we're left with 415.
Grab the next digit (1) from the dividend, add it to 415, then carry on: 4151 / 420

Step 7:
420 goes into 4151 9 times with a remainder of 371.
The next digit of our result is 9. 
Result so far: 3359.0
The remainder is 371 after subtracting 3780 from 4151.
Take the next digit (2) from the dividend and append it to 371, then repeat: 3712 / 420

Let's proceed to step 8:
3712 divided by 420 is 8 with a remainder of 352.
Record the quotient 8 as the next digit in the result. 
Result so far: 33598.0
If we take 3360 away from 3712, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 9:
3520 divided by 420 is 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 33598.8
Deduct 3360 from 3520 and we're left 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.

Moving on to step 10:
1600 divided by 420 is 3 with a remainder of 340.
The number 3 becomes the next digit in our result. 
Result so far: 33598.83
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.

Step 11:
420 goes into 3400 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 33598.838
Deduct 3360 from 3400 and we're left 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.

Advancing to step 12:
The number 420 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 33598.838
If we subtract 0 from 400, we get 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 13:
420 can be fit into 4000 9 times, resulting in a remainder of 220.
The number 9 becomes the next digit in our result. 
Result so far: 33598.83809
Subtract 3780 from 4000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
420 goes into 2200 5 times with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 33598.838095
The remainder is 100 after subtracting 2100 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
When dividing 1000 by 420, we get 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 33598.8380952
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.

Moving on to step 16:
1600 divided by 420 is 3 with a remainder of 340.
Use 3 as the next digit of our solution. 
Result so far: 33598.83809523
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.

The final result is 33598.83809523 with a remainder of 3.4e-07.
