20924616 ÷ 420 
We're looking to find how many times 420 goes into 20924616.

Step 1:
If we divide 2 by 420, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 420

On to step 2:
420 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 420

On to step 3:
209 divided by 420 is 0 with a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 209, we get 209.
Take the next digit (2) from the dividend and append it to 209, then repeat: 2092 / 420

Advancing to step 4:
420 can be fit into 2092 4 times, resulting in a remainder of 412.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 1680 from 2092 and we're left with 412.
Grab the next digit (4) from the dividend, add it to 412, then carry on: 4124 / 420

Step 5:
If we divide 4124 by 420, we get 9 and a remainder of 344.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 344 after subtracting 3780 from 4124.
Grab the next digit (6) from the dividend, add it to 344, then carry on: 3446 / 420

Going ahead to step 6:
When dividing 3446 by 420, we get 8 with a remainder of 86.
Use 8 as the next digit of our solution. 
Result so far: 498.0
Subtract 3360 from 3446 to get 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 420

Step 7:
420 goes into 861 2 times with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 4982.0
Deduct 840 from 861 and we're left with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 420

Advancing to step 8:
When dividing 216 by 420, we get 0 with a remainder of 216.
Use 0 as the next digit of our solution. 
Result so far: 49820.0
Subtracting 0 from 216 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 9:
If we divide 2160 by 420, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 49820.5
If we subtract 2100 from 2160, we get 60.
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 10:
The number 420 fits into 600 1 times, leaving a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 49820.51
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
When dividing 1800 by 420, we get 4 with a remainder of 120.
The next digit of our result is 4. 
Result so far: 49820.514
Deduct 1680 from 1800 and we're left 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.

Let's proceed to step 12:
When dividing 1200 by 420, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 49820.5142
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 13:
420 goes into 3600 8 times with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 49820.51428
If we subtract 3360 from 3600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
420 goes into 2400 5 times with a remainder of 300.
The next digit of our result is 5. 
Result so far: 49820.514285
Subtracting 2100 from 2400 leaves us 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.

Advancing to step 15:
The number 420 fits into 3000 7 times, leaving a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 49820.5142857
Subtracting 2940 from 3000 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.

Moving on to step 16:
420 goes into 600 1 times with a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 49820.51428571
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.

The final result is 49820.51428571 with a remainder of 1.8e-07.
