We look at the division of 136378 by 84 
We're looking to find how many times 84 goes into 136378.

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
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 84

Going ahead to step 2:
If we divide 13 by 84, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 84

On to step 3:
The number 84 fits into 136 1 times, leaving a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 84 from 136, we get 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 84

Moving on to step 4:
84 goes into 523 6 times with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 504 away from 523, we end up with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 84

Let's proceed to step 5:
84 can be fit into 197 2 times, resulting in a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 162.0
If we take 168 away from 197, we end up with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 84

Moving on to step 6:
When dividing 298 by 84, we get 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 1623.0
Subtract 252 from 298 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
When dividing 460 by 84, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 1623.5
If we subtract 420 from 460, we 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.

On to step 8:
400 divided by 84 is 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1623.54
Subtract 336 from 400 to 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.

Going ahead to step 9:
When dividing 640 by 84, we get 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 1623.547
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 10:
84 goes into 520 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1623.5476
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.

On to step 11:
84 goes into 160 1 times with a remainder of 76.
The next digit of our result is 1. 
Result so far: 1623.54761
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.

Step 12:
84 can be fit into 760 9 times, resulting in a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 1623.547619
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.

Let's proceed to step 13:
84 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1623.547619
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.

Step 14:
84 goes into 400 4 times with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1623.54761904
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.

The final outcome is 1623.54761904, with a leftover of 6.4e-08.
