18436 divided by 84 
We want to figure out the number of times 18436 can be divided by 84.

Step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 84

Going ahead to step 2:
If we divide 18 by 84, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 84

Moving on to step 3:
If we divide 184 by 84, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 168 from 184 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 84

Advancing to step 4:
The number 84 fits into 163 1 times, leaving a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 84 away from 163, we end up with 79.
Fetch the next digit (6) from the dividend, attach it to 79 and continue: 796 / 84

Step 5:
84 goes into 796 9 times with a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
The remainder is 40 after subtracting 756 from 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 6:
84 can be fit into 400 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 219.4
Deduct 336 from 400 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
The number 84 fits into 640 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 219.47
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
If we divide 520 by 84, we get 6 and a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 219.476
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 9:
When dividing 160 by 84, we get 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 219.4761
Subtract 84 from 160 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
The number 84 fits into 760 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.47619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
When dividing 40 by 84, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 219.47619
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
400 divided by 84 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 219.4761904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
When dividing 640 by 84, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 219.47619047
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 219.47619047, and the remainder is 5.2e-08.
