43237911 ÷ 70 
We want to figure out the number of times 43237911 can be divided by 70.

Going ahead to step 1:
If we divide 4 by 70, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 70

On to step 2:
70 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 70

Let's proceed to step 3:
70 can be fit into 432 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 12 after subtracting 420 from 432.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 70

Let's proceed to step 4:
When dividing 123 by 70, we get 1 with a remainder of 53.
The next digit of our result is 1. 
Result so far: 61.0
If we subtract 70 from 123, we get 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 70

On to step 5:
The number 70 fits into 537 7 times, leaving a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 617.0
Deduct 490 from 537 and we're left with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 70

Going ahead to step 6:
70 goes into 479 6 times with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 6176.0
If we take 420 away from 479, we end up with 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 70

Going ahead to step 7:
70 can be fit into 591 8 times, resulting in a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 61768.0
The remainder is 31 after subtracting 560 from 591.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 70

Advancing to step 8:
If we divide 311 by 70, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 617684.0
If we take 280 away from 311, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
310 divided by 70 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 617684.4
Deduct 280 from 310 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.

Advancing to step 10:
If we divide 300 by 70, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 617684.44
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 617684.44 with a remaining 0.02.
