67278528 ÷ 420 
We're looking to find how many times 420 goes into 67278528.

Going ahead to step 1:
If we divide 6 by 420, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 420

Moving on to step 2:
If we divide 67 by 420, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Fetch the next digit (2) from the dividend, attach it to 67 and continue: 672 / 420

On to step 3:
When dividing 672 by 420, we get 1 with a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 420 from 672 leaves us with 252.
Bring next digit (7) of the dividend behind the 252 and repeat the process: 2527 / 420

On to step 4:
When dividing 2527 by 420, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2520 from 2527 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 420

Moving on to step 5:
78 divided by 420 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we subtract 0 from 78, we get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 420

Advancing to step 6:
785 divided by 420 is 1 with a remainder of 365.
Write down 1 as next digit of the result. 
Result so far: 1601.0
Subtract 420 from 785 to get 365.
Fetch the next digit (2) from the dividend, attach it to 365 and continue: 3652 / 420

Going ahead to step 7:
If we divide 3652 by 420, we get 8 and a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 16018.0
Subtract 3360 from 3652 to get 292.
Take the next digit (8) from the dividend and append it to 292, then repeat: 2928 / 420

Step 8:
When dividing 2928 by 420, we get 6 with a remainder of 408.
Write down 6 as next digit of the result. 
Result so far: 160186.0
Subtracting 2520 from 2928 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 9:
When dividing 4080 by 420, we get 9 with a remainder of 300.
Write down 9 as next digit of the result. 
Result so far: 160186.9
The remainder is 300 after subtracting 3780 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 10:
420 goes into 3000 7 times with a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 160186.97
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.

Going ahead to step 11:
If we divide 600 by 420, we get 1 and a remainder of 180.
Write down 1 as next digit of the result. 
Result so far: 160186.971
Deduct 420 from 600 and we're left 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.

Step 12:
1800 divided by 420 is 4 with a remainder of 120.
The next digit of our result is 4. 
Result so far: 160186.9714
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 13:
420 goes into 1200 2 times with a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 160186.97142
Deduct 840 from 1200 and we're left with 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 14:
420 goes into 3600 8 times with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 160186.971428
Subtract 3360 from 3600 to 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.

Let's proceed to step 15:
The number 420 fits into 2400 5 times, leaving a remainder of 300.
Record the quotient 5 as the next digit in the result. 
Result so far: 160186.9714285
If we subtract 2100 from 2400, we get 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 16:
3000 divided by 420 is 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 160186.97142857
If we take 2940 away from 3000, we end up 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.

The quotient of the division is 160186.97142857, and the remainder is 6e-08.
