904641 ÷ 70 
We want to figure out the number of times 904641 can be divided by 70.

Let's proceed to step 1:
9 divided by 70 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 70

On to step 2:
70 can be fit into 90 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 70 from 90 leaves us with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 70

Going ahead to step 3:
70 goes into 204 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 64 after subtracting 140 from 204.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 70

Moving on to step 4:
When dividing 646 by 70, we get 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 129.0
The remainder is 16 after subtracting 630 from 646.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 70

On to step 5:
70 can be fit into 164 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
Deduct 140 from 164 and we're left with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 70

Moving on to step 6:
The number 70 fits into 241 3 times, leaving a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 12923.0
If we subtract 210 from 241, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
The number 70 fits into 310 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 12923.4
The remainder is 30 after subtracting 280 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
70 goes into 300 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12923.44
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.

The final result is 12923.44 with a remainder of 0.02.
