We're dividing 28478764 by 420 
Let's see how many times 420 fits into 28478764.

Moving on to 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
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 420

Advancing to step 2:
The number 420 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 420

Going ahead to step 3:
The number 420 fits into 284 0 times, leaving a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 284 to get 284.
Fetch the next digit (7) from the dividend, attach it to 284 and continue: 2847 / 420

Step 4:
420 goes into 2847 6 times with a remainder of 327.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 327 after subtracting 2520 from 2847.
Append the next digit (8) from the dividend to 327 and continue with: 3278 / 420

Moving on to step 5:
3278 divided by 420 is 7 with a remainder of 338.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we take 2940 away from 3278, we end up with 338.
Grab the next digit (7) from the dividend, add it to 338, then carry on: 3387 / 420

Let's proceed to step 6:
3387 divided by 420 is 8 with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 678.0
Subtract 3360 from 3387 to get 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 420

On to step 7:
420 can be fit into 276 0 times, resulting in a remainder of 276.
The number 0 becomes the next digit in our result. 
Result so far: 6780.0
Subtract 0 from 276 to get 276.
Take the next digit (4) from the dividend and append it to 276, then repeat: 2764 / 420

Step 8:
2764 divided by 420 is 6 with a remainder of 244.
Write down 6 as next digit of the result. 
Result so far: 67806.0
If we take 2520 away from 2764, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 9:
When dividing 2440 by 420, we get 5 with a remainder of 340.
Record the quotient 5 as the next digit in the result. 
Result so far: 67806.5
If we subtract 2100 from 2440, 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 10:
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: 67806.58
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.

Step 11:
420 goes into 400 0 times with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 67806.58
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
When dividing 4000 by 420, we get 9 with a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 67806.5809
If we subtract 3780 from 4000, we 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 13:
420 can be fit into 2200 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 67806.58095
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.

Step 14:
420 goes into 1000 2 times with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 67806.580952
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.

Step 15:
420 can be fit into 1600 3 times, resulting in a remainder of 340.
The next digit of our result is 3. 
Result so far: 67806.5809523
Subtract 1260 from 1600 to 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 16:
3400 divided by 420 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 67806.58095238
Subtract 3360 from 3400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 67806.58095238 with a remaining 4e-08.
