We look at the division of 90304406 by 70 
We're looking to find how many times 70 goes into 90304406.

Let's proceed to step 1:
When dividing 9 by 70, we get 0 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.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 70

Step 2:
70 goes into 90 1 times with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 70 from 90 and we're left with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 70

Moving on to step 3:
203 divided by 70 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 140 from 203 leaves us with 63.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 70

Advancing to step 4:
630 divided by 70 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 129.0
Subtracting 630 from 630 leaves us with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 70

Advancing to step 5:
If we divide 4 by 70, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 1290.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 70

Advancing to step 6:
The number 70 fits into 44 0 times, leaving a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 12900.0
If we subtract 0 from 44, we get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 70

On to step 7:
70 goes into 440 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 129006.0
Deduct 420 from 440 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 70

Advancing to step 8:
70 goes into 206 2 times with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 1290062.0
If we subtract 140 from 206, 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 9:
When dividing 660 by 70, we get 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 1290062.9
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.

Step 10:
300 divided by 70 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1290062.94
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.

Advancing to step 11:
The number 70 fits into 200 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 1290062.942
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.

Let's proceed to step 12:
If we divide 600 by 70, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1290062.9428
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.

Advancing to step 13:
400 divided by 70 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1290062.94285
The remainder is 50 after subtracting 350 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
500 divided by 70 is 7 with a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 1290062.942857
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.

Going ahead to step 15:
The number 70 fits into 100 1 times, leaving a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1290062.9428571
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.

Going ahead to step 16:
The number 70 fits into 300 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1290062.94285714
If we take 280 away from 300, we end up 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 1290062.94285714 with a remaining 2e-08.
