18964214 ÷ 420 
We're looking to find how many times 420 goes into 18964214.

Going ahead to step 1:
If we divide 1 by 420, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 420

Advancing to step 2:
When dividing 18 by 420, we get 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 420

Let's proceed to step 3:
420 goes into 189 0 times with a remainder of 189.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 189 to get 189.
Grab the next digit (6) from the dividend, add it to 189, then carry on: 1896 / 420

Moving on to step 4:
The number 420 fits into 1896 4 times, leaving a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 1680 from 1896 to get 216.
Include the next digit (4) from the dividend after 216, then repeat: 2164 / 420

Step 5:
When dividing 2164 by 420, we get 5 with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 64 after subtracting 2100 from 2164.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 420

Let's proceed to step 6:
When dividing 642 by 420, we get 1 with a remainder of 222.
Put 1 as the next digit of the answer. 
Result so far: 451.0
The remainder is 222 after subtracting 420 from 642.
Grab the next digit (1) from the dividend, add it to 222, then carry on: 2221 / 420

Advancing to step 7:
When dividing 2221 by 420, we get 5 with a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 4515.0
If we subtract 2100 from 2221, we get 121.
Append the next digit (4) from the dividend to 121 and continue with: 1214 / 420

Moving on to step 8:
If we divide 1214 by 420, we get 2 and a remainder of 374.
Put 2 as the next digit of the answer. 
Result so far: 45152.0
If we subtract 840 from 1214, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 9:
420 can be fit into 3740 8 times, resulting in a remainder of 380.
Record the quotient 8 as the next digit in the result. 
Result so far: 45152.8
The remainder is 380 after subtracting 3360 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
If we divide 3800 by 420, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 45152.89
Subtract 3780 from 3800 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
420 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 45152.89
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
The number 420 fits into 2000 4 times, leaving a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 45152.8904
Deduct 1680 from 2000 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 13:
420 goes into 3200 7 times with a remainder of 260.
Record the quotient 7 as the next digit in the result. 
Result so far: 45152.89047
Subtracting 2940 from 3200 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
The number 420 fits into 2600 6 times, leaving a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 45152.890476
Subtract 2520 from 2600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
420 goes into 800 1 times with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 45152.8904761
If we subtract 420 from 800, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 16:
3800 divided by 420 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 45152.89047619
If we take 3780 away from 3800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 45152.89047619 with a remainder of 2e-08.
