Let's divide 81900950 by 84
We want to divide 81900950 by 84.

Moving on to step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 84

Going ahead to step 2:
The number 84 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 84

Advancing to step 3:
84 can be fit into 819 9 times, resulting in a remainder of 63.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 63 after subtracting 756 from 819.
Append the next digit (0) from the dividend to 63 and continue with: 630 / 84

Moving on to step 4:
If we divide 630 by 84, we get 7 and a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 588 from 630 to get 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 84

On to step 5:
When dividing 420 by 84, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 975.0
If we take 420 away from 420, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 84

Going ahead to step 6:
84 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 9750.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 84

Step 7:
When dividing 95 by 84, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 97501.0
Subtracting 84 from 95 leaves us with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 84

Advancing to step 8:
If we divide 110 by 84, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 975011.0
If we take 84 away from 110, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
The number 84 fits into 260 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 975011.3
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 84, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 975011.3
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 975011.309
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 975011.3095
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
If we divide 200 by 84, we get 2 and a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 975011.30952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 84, we get 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 975011.309523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 15:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 975011.3095238
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 16:
When dividing 80 by 84, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 975011.3095238
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 975011.3095238, with a leftover of 8e-08.
