902579 ÷ 70 
Our goal is to divide 902579 by 70.

On 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
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 70

Moving on to step 2:
90 divided by 70 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 70 from 90 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 70

Going ahead to step 3:
202 divided by 70 is 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 62 after subtracting 140 from 202.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 70

Going ahead to step 4:
70 can be fit into 625 8 times, resulting in a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 65 after subtracting 560 from 625.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 70

Advancing to step 5:
If we divide 657 by 70, we get 9 and a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 1289.0
If we take 630 away from 657, we end up with 27.
Fetch the next digit (9) from the dividend, attach it to 27 and continue: 279 / 70

Moving on to step 6:
70 goes into 279 3 times with a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 12893.0
The remainder is 69 after subtracting 210 from 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
690 divided by 70 is 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 12893.9
If we take 630 away from 690, 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.

Going ahead to step 8:
70 goes into 600 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 12893.98
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 70 fits into 400 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12893.985
If we subtract 350 from 400, we 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.

Step 10:
If we divide 500 by 70, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 12893.9857
Subtracting 490 from 500 leaves us 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.

Going ahead to step 11:
70 goes into 100 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 12893.98571
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 12:
70 goes into 300 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12893.985714
If we subtract 280 from 300, we 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.

Moving on to step 13:
If we divide 200 by 70, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 12893.9857142
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.

On to step 14:
If we divide 600 by 70, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 12893.98571428
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.

After the division, we end up with 12893.98571428 and a remainder of 4e-08.
