Moving on to step 3:
423 divided by 138 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 414 from 423, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 138

Moving on to step 4:
The number 138 fits into 97 0 times, leaving a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (6) from the dividend, attach it to 97 and continue: 976 / 138

On to step 5:
The number 138 fits into 976 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 307.0
Subtracting 966 from 976 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 138

Advancing to step 6:
The number 138 fits into 108 0 times, leaving a remainder of 108.
Record the quotient 0 as the next digit in the result. 
Result so far: 3070.0
Subtracting 0 from 108 leaves us with 108.
Append the next digit (5) from the dividend to 108 and continue with: 1085 / 138

Going ahead to step 7:
If we divide 1085 by 138, we get 7 and a remainder of 119.
Write down 7 as next digit of the result. 
Result so far: 30707.0
Subtract 966 from 1085 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 8:
The number 138 fits into 1190 8 times, leaving a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 30707.8
The remainder is 86 after subtracting 1104 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
The number 138 fits into 860 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 30707.86
If we take 828 away from 860, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 138, we get 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 30707.862
If we subtract 276 from 320, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
138 can be fit into 440 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 30707.8623
The remainder is 26 after subtracting 414 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
138 can be fit into 260 1 times, resulting in a remainder of 122.
Write down 1 as next digit of the result. 
Result so far: 30707.86231
The remainder is 122 after subtracting 138 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 13:
138 goes into 1220 8 times with a remainder of 116.
Write down 8 as next digit of the result. 
Result so far: 30707.862318
Deduct 1104 from 1220 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 14:
138 can be fit into 1160 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 30707.8623188
Subtracting 1104 from 1160 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 30707.8623188 with a balance of 5.6e-07.
