We're dividing 81998731 by 50 
We want to figure out the number of times 81998731 can be divided by 50.

Let's proceed to step 1:
50 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 50

On to step 2:
50 can be fit into 81 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 50 away from 81, we end up with 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 50

Let's proceed to step 3:
50 goes into 319 6 times with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 300 from 319 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 50

Going ahead to step 4:
199 divided by 50 is 3 with a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Deduct 150 from 199 and we're left with 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 50

Let's proceed to step 5:
When dividing 498 by 50, we get 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 1639.0
Deduct 450 from 498 and we're left with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 50

Moving on to step 6:
When dividing 487 by 50, we get 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 16399.0
If we take 450 away from 487, we end up with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 50

Let's proceed to step 7:
When dividing 373 by 50, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 163997.0
The remainder is 23 after subtracting 350 from 373.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 50

Moving on to step 8:
50 goes into 231 4 times with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 1639974.0
The remainder is 31 after subtracting 200 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
When dividing 310 by 50, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 1639974.6
If we subtract 300 from 310, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 50, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1639974.62
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1639974.62
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1639974.62
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1639974.62, with a leftover of 0.0.
