On to step 1:
7 divided by 138 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 138

Advancing to step 2:
71 divided by 138 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 138

Let's proceed to step 3:
138 goes into 718 5 times with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 690 from 718 leaves us with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 138

Going ahead to step 4:
If we divide 284 by 138, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 276 away from 284, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 138

Going ahead to step 5:
If we divide 81 by 138, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 520.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (8) from the dividend to 81 and continue with: 818 / 138

Going ahead to step 6:
The number 138 fits into 818 5 times, leaving a remainder of 128.
Write down 5 as next digit of the result. 
Result so far: 5205.0
If we subtract 690 from 818, we get 128.
Take the next digit (6) from the dividend and append it to 128, then repeat: 1286 / 138

On to step 7:
The number 138 fits into 1286 9 times, leaving a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 52059.0
The remainder is 44 after subtracting 1242 from 1286.
Grab the next digit (9) from the dividend, add it to 44, then carry on: 449 / 138

Moving on to step 8:
If we divide 449 by 138, we get 3 and a remainder of 35.
The next digit of our result is 3. 
Result so far: 520593.0
Subtract 414 from 449 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
350 divided by 138 is 2 with a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 520593.2
Subtracting 276 from 350 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
138 goes into 740 5 times with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 520593.25
Subtract 690 from 740 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
138 can be fit into 500 3 times, resulting in a remainder of 86.
Write down 3 as next digit of the result. 
Result so far: 520593.253
The remainder is 86 after subtracting 414 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
860 divided by 138 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 520593.2536
If we subtract 828 from 860, we get 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 13:
320 divided by 138 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 520593.25362
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.

Advancing to step 14:
The number 138 fits into 440 3 times, leaving a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 520593.253623
Subtract 414 from 440 to get 26.
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 15:
138 goes into 260 1 times with a remainder of 122.
Record the quotient 1 as the next digit in the result. 
Result so far: 520593.2536231
Subtract 138 from 260 to get 122.
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 16:
The number 138 fits into 1220 8 times, leaving a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 520593.25362318
Subtract 1104 from 1220 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 520593.25362318, and the remainder is 1.16e-07.
