We divide 42436417 by 531
Our goal is to divide 42436417 by 531.

Moving on to step 1:
531 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 531

Let's proceed to step 2:
531 goes into 42 0 times with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 531

Advancing to step 3:
424 divided by 531 is 0 with a remainder of 424.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 424, we end up with 424.
Fetch the next digit (3) from the dividend, attach it to 424 and continue: 4243 / 531

Step 4:
531 goes into 4243 7 times with a remainder of 526.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 3717 from 4243 to get 526.
Take the next digit (6) from the dividend and append it to 526, then repeat: 5266 / 531

Let's proceed to step 5:
531 goes into 5266 9 times with a remainder of 487.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 4779 from 5266, we get 487.
Grab the next digit (4) from the dividend, add it to 487, then carry on: 4874 / 531

Advancing to step 6:
531 goes into 4874 9 times with a remainder of 95.
Put 9 as the next digit of the answer. 
Result so far: 799.0
Deduct 4779 from 4874 and we're left with 95.
Include the next digit (1) from the dividend after 95, then repeat: 951 / 531

Step 7:
If we divide 951 by 531, we get 1 and a remainder of 420.
Write down 1 as next digit of the result. 
Result so far: 7991.0
If we take 531 away from 951, we end up with 420.
Include the next digit (7) from the dividend after 420, then repeat: 4207 / 531

Going ahead to step 8:
531 goes into 4207 7 times with a remainder of 490.
Write down 7 as next digit of the result. 
Result so far: 79917.0
Subtract 3717 from 4207 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 9:
If we divide 4900 by 531, we get 9 and a remainder of 121.
Put 9 as the next digit of the answer. 
Result so far: 79917.9
If we subtract 4779 from 4900, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 10:
531 can be fit into 1210 2 times, resulting in a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 79917.92
Deduct 1062 from 1210 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
531 goes into 1480 2 times with a remainder of 418.
The next digit of our result is 2. 
Result so far: 79917.922
Subtracting 1062 from 1480 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 79917.922, with a leftover of 0.0418.
