We look at the division of 421186 by 70 
We're looking to find how many times 70 goes into 421186.

Advancing to step 1:
The number 70 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 70

Step 2:
42 divided by 70 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 70

Moving on to step 3:
The number 70 fits into 421 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 420 from 421 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 70

On to step 4:
70 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 70

Advancing to step 5:
The number 70 fits into 118 1 times, leaving a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 601.0
If we take 70 away from 118, we end up with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 70

On to step 6:
70 goes into 486 6 times with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 6016.0
If we subtract 420 from 486, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
70 can be fit into 660 9 times, resulting in a remainder of 30.
The next digit of our result is 9. 
Result so far: 6016.9
If we subtract 630 from 660, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
70 can be fit into 300 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 6016.94
Subtract 280 from 300 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.

On to step 9:
The number 70 fits into 200 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 6016.942
Deduct 140 from 200 and we're left 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.

Let's proceed to step 10:
When dividing 600 by 70, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 6016.9428
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
70 can be fit into 400 5 times, resulting in a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6016.94285
Subtract 350 from 400 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
500 divided by 70 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 6016.942857
If we take 490 away from 500, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
100 divided by 70 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 6016.9428571
Deduct 70 from 100 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
70 can be fit into 300 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 6016.94285714
Subtracting 280 from 300 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.

Our division results in 6016.94285714 with a remaining 2e-08.
