Let's divide 109138 by 84
Our goal is to divide 109138 by 84.

On to step 1:
1 divided by 84 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 84

Advancing to step 2:
84 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 84

On to step 3:
The number 84 fits into 109 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 84 from 109, we get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 84

Advancing to step 4:
The number 84 fits into 251 2 times, leaving a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 168 from 251 and we're left with 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 84

Going ahead to step 5:
The number 84 fits into 833 9 times, leaving a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Deduct 756 from 833 and we're left with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 84

Moving on to step 6:
If we divide 778 by 84, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 1299.0
Deduct 756 from 778 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 84, we get 2 and a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 1299.2
If we take 168 away from 220, we end up 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.

Going ahead to step 8:
520 divided by 84 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 1299.26
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.

Advancing to step 9:
84 goes into 160 1 times with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 1299.261
Deduct 84 from 160 and we're left with 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:
When dividing 760 by 84, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 1299.2619
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.

Going ahead to step 11:
When dividing 40 by 84, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1299.2619
Deduct 0 from 40 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.

Let's proceed to step 12:
84 can be fit into 400 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 1299.261904
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.

Moving on to step 13:
If we divide 640 by 84, we get 7 and a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 1299.2619047
If we take 588 away from 640, we end up 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.

On to step 14:
520 divided by 84 is 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1299.26190476
Deduct 504 from 520 and we're left 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.

The final outcome is 1299.26190476, with a leftover of 1.6e-08.
