Let's divide 16021988 by 84
Our goal is to divide 16021988 by 84.

Step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 84

Let's proceed to step 2:
If we divide 16 by 84, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 84

Going ahead to step 3:
If we divide 160 by 84, we get 1 and a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 84 from 160 and we're left with 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 84

Moving on to step 4:
84 can be fit into 762 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 6 after subtracting 756 from 762.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 84

Going ahead to step 5:
61 divided by 84 is 0 with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we subtract 0 from 61, we get 61.
Grab the next digit (9) from the dividend, add it to 61, then carry on: 619 / 84

Moving on to step 6:
If we divide 619 by 84, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 1907.0
Deduct 588 from 619 and we're left with 31.
Take the next digit (8) from the dividend and append it to 31, then repeat: 318 / 84

Let's proceed to step 7:
84 goes into 318 3 times with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 19073.0
Subtracting 252 from 318 leaves us with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 84

On to step 8:
668 divided by 84 is 7 with a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 190737.0
If we take 588 away from 668, we end up 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.

Going ahead to step 9:
84 goes into 800 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 190737.9
Subtract 756 from 800 to get 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 10:
If we divide 440 by 84, we get 5 and a remainder of 20.
The next digit of our result is 5. 
Result so far: 190737.95
The remainder is 20 after subtracting 420 from 440.
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 11:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 190737.952
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
84 goes into 320 3 times with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 190737.9523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 190737.95238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 190737.95238
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
800 divided by 84 is 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 190737.9523809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 16:
84 goes into 440 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 190737.95238095
If we take 420 away from 440, we end up 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.

The final outcome is 190737.95238095, with a leftover of 2e-08.
