70473942 ÷ 581 
We want to figure out the number of times 70473942 can be divided by 581.

Going ahead to step 1:
The number 581 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 581

Let's proceed to step 2:
The number 581 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Grab the next digit (4) from the dividend, add it to 70, then carry on: 704 / 581

Let's proceed to step 3:
The number 581 fits into 704 1 times, leaving a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 581 from 704 leaves us with 123.
Take the next digit (7) from the dividend and append it to 123, then repeat: 1237 / 581

Let's proceed to step 4:
The number 581 fits into 1237 2 times, leaving a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1162 from 1237 to get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 581

On to step 5:
753 divided by 581 is 1 with a remainder of 172.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtract 581 from 753 to get 172.
Take the next digit (9) from the dividend and append it to 172, then repeat: 1729 / 581

Going ahead to step 6:
If we divide 1729 by 581, we get 2 and a remainder of 567.
Record the quotient 2 as the next digit in the result. 
Result so far: 1212.0
The remainder is 567 after subtracting 1162 from 1729.
Fetch the next digit (4) from the dividend, attach it to 567 and continue: 5674 / 581

On to step 7:
581 can be fit into 5674 9 times, resulting in a remainder of 445.
Put 9 as the next digit of the answer. 
Result so far: 12129.0
Subtract 5229 from 5674 to get 445.
Take the next digit (2) from the dividend and append it to 445, then repeat: 4452 / 581

On to step 8:
If we divide 4452 by 581, we get 7 and a remainder of 385.
Use 7 as the next digit of our solution. 
Result so far: 121297.0
If we take 4067 away from 4452, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 9:
The number 581 fits into 3850 6 times, leaving a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 121297.6
Subtracting 3486 from 3850 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 10:
3640 divided by 581 is 6 with a remainder of 154.
The next digit of our result is 6. 
Result so far: 121297.66
If we subtract 3486 from 3640, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

After the division, we end up with 121297.66 and a remainder of 0.154.
