13395405 ÷ 138 
Our goal is to divide 13395405 by 138.

Let's proceed to step 1:
The number 138 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
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 / 138

Advancing to step 2:
If we divide 13 by 138, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 138

Step 3:
When dividing 133 by 138, we get 0 with a remainder of 133.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 133 and we're left with 133.
Include the next digit (9) from the dividend after 133, then repeat: 1339 / 138

Advancing to step 4:
The number 138 fits into 1339 9 times, leaving a remainder of 97.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 1242 from 1339 to get 97.
Take the next digit (5) from the dividend and append it to 97, then repeat: 975 / 138

On to step 5:
If we divide 975 by 138, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we subtract 966 from 975, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 138

Step 6:
138 goes into 94 0 times with a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 970.0
Subtract 0 from 94 to get 94.
Append the next digit (0) from the dividend to 94 and continue with: 940 / 138

Moving on to step 7:
138 can be fit into 940 6 times, resulting in a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 9706.0
If we subtract 828 from 940, we get 112.
Bring next digit (5) of the dividend behind the 112 and repeat the process: 1125 / 138

Let's proceed to step 8:
138 goes into 1125 8 times with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 97068.0
The remainder is 21 after subtracting 1104 from 1125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 9:
The number 138 fits into 210 1 times, leaving a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 97068.1
Subtract 138 from 210 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
The number 138 fits into 720 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 97068.15
If we subtract 690 from 720, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 138 fits into 300 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 97068.152
Subtracting 276 from 300 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 138 is 1 with a remainder of 102.
Use 1 as the next digit of our solution. 
Result so far: 97068.1521
Subtract 138 from 240 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 13:
If we divide 1020 by 138, we get 7 and a remainder of 54.
The next digit of our result is 7. 
Result so far: 97068.15217
The remainder is 54 after subtracting 966 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
138 can be fit into 540 3 times, resulting in a remainder of 126.
Record the quotient 3 as the next digit in the result. 
Result so far: 97068.152173
The remainder is 126 after subtracting 414 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 15:
The number 138 fits into 1260 9 times, leaving a remainder of 18.
The next digit of our result is 9. 
Result so far: 97068.1521739
If we take 1242 away from 1260, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 16:
If we divide 180 by 138, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 97068.15217391
If we subtract 138 from 180, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 97068.15217391 and a remainder of 4.2e-08.
