Let's divide 42012644 by 437
We're looking to find how many times 437 goes into 42012644.

Moving on to step 1:
When dividing 4 by 437, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 437

Step 2:
437 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 437

Moving on to step 3:
When dividing 420 by 437, we get 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 420, we get 420.
Grab the next digit (1) from the dividend, add it to 420, then carry on: 4201 / 437

On to step 4:
437 goes into 4201 9 times with a remainder of 268.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 3933 from 4201 leaves us with 268.
Fetch the next digit (2) from the dividend, attach it to 268 and continue: 2682 / 437

On to step 5:
If we divide 2682 by 437, we get 6 and a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 2622 from 2682 to get 60.
Bring next digit (6) of the dividend behind the 60 and repeat the process: 606 / 437

Going ahead to step 6:
606 divided by 437 is 1 with a remainder of 169.
Record the quotient 1 as the next digit in the result. 
Result so far: 961.0
If we subtract 437 from 606, we get 169.
Include the next digit (4) from the dividend after 169, then repeat: 1694 / 437

Step 7:
The number 437 fits into 1694 3 times, leaving a remainder of 383.
Put 3 as the next digit of the answer. 
Result so far: 9613.0
Subtract 1311 from 1694 to get 383.
Grab the next digit (4) from the dividend, add it to 383, then carry on: 3834 / 437

Advancing to step 8:
437 goes into 3834 8 times with a remainder of 338.
Put 8 as the next digit of the answer. 
Result so far: 96138.0
Subtracting 3496 from 3834 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
437 can be fit into 3380 7 times, resulting in a remainder of 321.
Use 7 as the next digit of our solution. 
Result so far: 96138.7
Deduct 3059 from 3380 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 10:
When dividing 3210 by 437, we get 7 with a remainder of 151.
The next digit of our result is 7. 
Result so far: 96138.77
Subtract 3059 from 3210 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

After the division, we end up with 96138.77 and a remainder of 0.151.
