137809 divided by 84 
We want to divide 137809 by 84.

Going ahead to step 1:
If we divide 1 by 84, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 84

Step 2:
If we divide 13 by 84, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 84

Advancing to step 3:
If we divide 137 by 84, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 84 from 137, we get 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 84

Moving on to step 4:
84 can be fit into 538 6 times, resulting in a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 504 away from 538, we end up with 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 84

Advancing to step 5:
The number 84 fits into 340 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 336 from 340, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 84

Advancing to step 6:
The number 84 fits into 49 0 times, leaving a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 1640.0
If we subtract 0 from 49, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
If we divide 490 by 84, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1640.5
Subtract 420 from 490 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
When dividing 700 by 84, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 1640.58
If we subtract 672 from 700, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
If we divide 280 by 84, we get 3 and a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 1640.583
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 84, we get 3 with a remainder of 28.
The next digit of our result is 3. 
Result so far: 1640.5833
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 1640.5833 with a remainder of 0.00028.
