We're dividing 18988235 by 138 
Let's see how many times 138 fits into 18988235.

On to step 1:
When dividing 1 by 138, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 138

Going ahead to step 2:
138 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 138

Moving on to step 3:
138 goes into 189 1 times with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 138 away from 189, we end up with 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 138

Step 4:
The number 138 fits into 518 3 times, leaving a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 414 from 518 and we're left with 104.
Grab the next digit (8) from the dividend, add it to 104, then carry on: 1048 / 138

Moving on to step 5:
The number 138 fits into 1048 7 times, leaving a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 966 from 1048 and we're left with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 138

Advancing to step 6:
138 can be fit into 822 5 times, resulting in a remainder of 132.
Record the quotient 5 as the next digit in the result. 
Result so far: 1375.0
If we take 690 away from 822, we end up with 132.
Fetch the next digit (3) from the dividend, attach it to 132 and continue: 1323 / 138

Advancing to step 7:
138 goes into 1323 9 times with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 13759.0
Deduct 1242 from 1323 and we're left with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 138

Moving on to step 8:
138 can be fit into 815 5 times, resulting in a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 137595.0
Deduct 690 from 815 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
If we divide 1250 by 138, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 137595.9
If we subtract 1242 from 1250, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 138, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 137595.9
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
800 divided by 138 is 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 137595.905
Deduct 690 from 800 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
138 goes into 1100 7 times with a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 137595.9057
If we subtract 966 from 1100, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 13:
138 goes into 1340 9 times with a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 137595.90579
Deduct 1242 from 1340 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 14:
138 can be fit into 980 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 137595.905797
Subtracting 966 from 980 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
140 divided by 138 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 137595.9057971
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 16:
The number 138 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 137595.9057971
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 137595.9057971 with a remaining 2e-08.
