We look at the division of 42793390 by 436 
Our goal is to divide 42793390 by 436.

On to step 1:
4 divided by 436 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 436

Advancing to step 2:
The number 436 fits into 42 0 times, leaving 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.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 436

Let's proceed to step 3:
436 can be fit into 427 0 times, resulting in a remainder of 427.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 427 and we're left with 427.
Bring next digit (9) of the dividend behind the 427 and repeat the process: 4279 / 436

Moving on to step 4:
The number 436 fits into 4279 9 times, leaving a remainder of 355.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3924 from 4279, we get 355.
Append the next digit (3) from the dividend to 355 and continue with: 3553 / 436

On to step 5:
If we divide 3553 by 436, we get 8 and a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Deduct 3488 from 3553 and we're left with 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 436

Step 6:
653 divided by 436 is 1 with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 981.0
The remainder is 217 after subtracting 436 from 653.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 436

On to step 7:
2179 divided by 436 is 4 with a remainder of 435.
The next digit of our result is 4. 
Result so far: 9814.0
If we subtract 1744 from 2179, we get 435.
Include the next digit (0) from the dividend after 435, then repeat: 4350 / 436

Moving on to step 8:
436 goes into 4350 9 times with a remainder of 426.
Write down 9 as next digit of the result. 
Result so far: 98149.0
Deduct 3924 from 4350 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 9:
When dividing 4260 by 436, we get 9 with a remainder of 336.
Record the quotient 9 as the next digit in the result. 
Result so far: 98149.9
The remainder is 336 after subtracting 3924 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 10:
3360 divided by 436 is 7 with a remainder of 308.
Record the quotient 7 as the next digit in the result. 
Result so far: 98149.97
Subtract 3052 from 3360 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 11:
If we divide 3080 by 436, we get 7 and a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 98149.977
If we take 3052 away from 3080, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 98149.977, with a leftover of 0.0028.
