70912421 ÷ 30 
Let's see how many times 30 fits into 70912421.

Moving on to step 1:
30 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 30

Moving on to step 2:
30 goes into 70 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 60 from 70 leaves us with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 30

Let's proceed to step 3:
The number 30 fits into 109 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 19 after subtracting 90 from 109.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 30

On to step 4:
30 goes into 191 6 times with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
Subtracting 180 from 191 leaves us with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 30

Going ahead to step 5:
If we divide 112 by 30, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 2363.0
If we subtract 90 from 112, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 30

Step 6:
If we divide 224 by 30, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 23637.0
If we subtract 210 from 224, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 30

Advancing to step 7:
142 divided by 30 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 236374.0
Subtracting 120 from 142 leaves us with 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 30

On to step 8:
The number 30 fits into 221 7 times, leaving a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 2363747.0
Deduct 210 from 221 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 30 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 2363747.3
Subtract 90 from 110 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.

On to step 10:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 2363747.36
The remainder is 20 after subtracting 180 from 200.
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 30, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 2363747.366
Subtract 180 from 200 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 outcome is 2363747.366, with a leftover of 0.002.
