We're dividing 139312 by 84 
Our goal is to divide 139312 by 84.

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

Moving on to step 2:
84 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 84

Step 3:
139 divided by 84 is 1 with a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 84 from 139, we get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 84

Going ahead to step 4:
When dividing 553 by 84, we get 6 with a remainder of 49.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 504 from 553 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 84

Advancing to step 5:
84 can be fit into 491 5 times, resulting in a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we take 420 away from 491, we end up with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 84

Step 6:
712 divided by 84 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1658.0
Deduct 672 from 712 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
If we divide 400 by 84, we get 4 and a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 1658.4
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.

Going ahead to step 8:
The number 84 fits into 640 7 times, leaving a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 1658.47
Deduct 588 from 640 and we're left with 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 9:
84 goes into 520 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1658.476
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
84 goes into 160 1 times with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1658.4761
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 11:
84 can be fit into 760 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1658.47619
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
40 divided by 84 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1658.47619
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
84 goes into 400 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1658.4761904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 1658.47619047
Deduct 588 from 640 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 1658.47619047 and a remainder of 5.2e-08.
