Let's divide 78998791 by 436
We want to divide 78998791 by 436.

Step 1:
436 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 436

Let's proceed to step 2:
78 divided by 436 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 436

Advancing to step 3:
436 goes into 789 1 times with a remainder of 353.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 436 from 789 and we're left with 353.
Include the next digit (9) from the dividend after 353, then repeat: 3539 / 436

Going ahead to step 4:
3539 divided by 436 is 8 with a remainder of 51.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3488 from 3539 and we're left with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 436

On to step 5:
If we divide 518 by 436, we get 1 and a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Subtracting 436 from 518 leaves us with 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 436

Moving on to step 6:
827 divided by 436 is 1 with a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 1811.0
Subtract 436 from 827 to get 391.
Fetch the next digit (9) from the dividend, attach it to 391 and continue: 3919 / 436

Advancing to step 7:
If we divide 3919 by 436, we get 8 and a remainder of 431.
Use 8 as the next digit of our solution. 
Result so far: 18118.0
Subtract 3488 from 3919 to get 431.
Append the next digit (1) from the dividend to 431 and continue with: 4311 / 436

Moving on to step 8:
436 can be fit into 4311 9 times, resulting in a remainder of 387.
Put 9 as the next digit of the answer. 
Result so far: 181189.0
The remainder is 387 after subtracting 3924 from 4311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 9:
436 goes into 3870 8 times with a remainder of 382.
Use 8 as the next digit of our solution. 
Result so far: 181189.8
Subtract 3488 from 3870 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Step 10:
When dividing 3820 by 436, we get 8 with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 181189.88
Subtract 3488 from 3820 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final outcome is 181189.88, with a leftover of 0.332.
