902090 ÷ 70 
We want to divide 902090 by 70.

Advancing to step 1:
70 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 70

Let's proceed to step 2:
90 divided by 70 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 70 from 90 leaves us with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 70

On to step 3:
202 divided by 70 is 2 with a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 140 from 202 leaves us with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 70

Advancing to step 4:
When dividing 620 by 70, we get 8 with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 128.0
If we subtract 560 from 620, we get 60.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 70

On to step 5:
If we divide 609 by 70, we get 8 and a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 1288.0
Subtracting 560 from 609 leaves us with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 70

Moving on to step 6:
The number 70 fits into 490 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 12887.0
Deduct 490 from 490 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 70 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12887.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 70 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12887.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12887.0 with a remaining 0.0.
