We're dividing 69878381 by 420 
We're looking to find how many times 420 goes into 69878381.

On to step 1:
420 goes into 6 0 times with 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.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 420

On to step 2:
420 can be fit into 69 0 times, resulting in a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 420

Let's proceed to step 3:
When dividing 698 by 420, we get 1 with a remainder of 278.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 420 from 698 to get 278.
Append the next digit (7) from the dividend to 278 and continue with: 2787 / 420

On to step 4:
420 goes into 2787 6 times with a remainder of 267.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 2520 from 2787 to get 267.
Take the next digit (8) from the dividend and append it to 267, then repeat: 2678 / 420

Going ahead to step 5:
420 goes into 2678 6 times with a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
Subtract 2520 from 2678 to get 158.
Bring next digit (3) of the dividend behind the 158 and repeat the process: 1583 / 420

Moving on to step 6:
If we divide 1583 by 420, we get 3 and a remainder of 323.
The next digit of our result is 3. 
Result so far: 1663.0
If we take 1260 away from 1583, we end up with 323.
Grab the next digit (8) from the dividend, add it to 323, then carry on: 3238 / 420

Going ahead to step 7:
If we divide 3238 by 420, we get 7 and a remainder of 298.
Record the quotient 7 as the next digit in the result. 
Result so far: 16637.0
Deduct 2940 from 3238 and we're left with 298.
Take the next digit (1) from the dividend and append it to 298, then repeat: 2981 / 420

Going ahead to step 8:
If we divide 2981 by 420, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 166377.0
Subtracting 2940 from 2981 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
If we divide 410 by 420, we get 0 and a remainder of 410.
The next digit of our result is 0. 
Result so far: 166377.0
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 10:
4100 divided by 420 is 9 with a remainder of 320.
The next digit of our result is 9. 
Result so far: 166377.09
Subtracting 3780 from 4100 leaves us 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.

On to step 11:
If we divide 3200 by 420, we get 7 and a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 166377.097
If we subtract 2940 from 3200, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
420 goes into 2600 6 times with a remainder of 80.
The next digit of our result is 6. 
Result so far: 166377.0976
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.

Advancing to step 13:
800 divided by 420 is 1 with a remainder of 380.
The number 1 becomes the next digit in our result. 
Result so far: 166377.09761
Deduct 420 from 800 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 14:
420 goes into 3800 9 times with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 166377.097619
Subtracting 3780 from 3800 leaves us 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.

Let's proceed to step 15:
200 divided by 420 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 166377.097619
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
420 goes into 2000 4 times with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 166377.09761904
If we subtract 1680 from 2000, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 166377.09761904, with a leftover of 3.2e-07.
