We divide 420859 by 70
We want to divide 420859 by 70.

Step 1:
70 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 70

Advancing to step 2:
When dividing 42 by 70, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 70

Let's proceed to step 3:
420 divided by 70 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 420 from 420, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 70

Advancing to step 4:
When dividing 8 by 70, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 70

Moving on to step 5:
When dividing 85 by 70, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 601.0
The remainder is 15 after subtracting 70 from 85.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 70

On to step 6:
When dividing 159 by 70, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 6012.0
Subtracting 140 from 159 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 70 fits into 190 2 times, leaving a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 6012.2
The remainder is 50 after subtracting 140 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
70 can be fit into 500 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 6012.27
If we subtract 490 from 500, we get 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 9:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 6012.271
Subtract 70 from 100 to 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.

Going ahead to step 10:
300 divided by 70 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 6012.2714
Deduct 280 from 300 and we're left 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.

Going ahead to step 11:
If we divide 200 by 70, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 6012.27142
Subtract 140 from 200 to 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.

On to step 12:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 6012.271428
Deduct 560 from 600 and we're left 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.

Advancing to step 13:
If we divide 400 by 70, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6012.2714285
Deduct 350 from 400 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
The number 70 fits into 500 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 6012.27142857
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.

Our division results in 6012.27142857 with a remaining 1e-08.
