Step 3:
138 can be fit into 842 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 828 away from 842, we end up with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 138

On to step 4:
138 goes into 140 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtract 138 from 140 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 138

On to step 5:
138 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 610.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 138

Moving on to step 6:
138 can be fit into 217 1 times, resulting in a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 6101.0
Subtracting 138 from 217 leaves us with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 138

Advancing to step 7:
138 can be fit into 791 5 times, resulting in a remainder of 101.
The next digit of our result is 5. 
Result so far: 61015.0
Subtracting 690 from 791 leaves us with 101.
Include the next digit (7) from the dividend after 101, then repeat: 1017 / 138

Moving on to step 8:
The number 138 fits into 1017 7 times, leaving a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 610157.0
Subtracting 966 from 1017 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
When dividing 510 by 138, we get 3 with a remainder of 96.
Write down 3 as next digit of the result. 
Result so far: 610157.3
Subtract 414 from 510 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
138 can be fit into 960 6 times, resulting in a remainder of 132.
The number 6 becomes the next digit in our result. 
Result so far: 610157.36
If we subtract 828 from 960, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 11:
1320 divided by 138 is 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 610157.369
If we subtract 1242 from 1320, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
138 can be fit into 780 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 610157.3695
Subtracting 690 from 780 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 13:
900 divided by 138 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 610157.36956
Subtracting 828 from 900 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
720 divided by 138 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 610157.369565
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.

On to step 15:
300 divided by 138 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 610157.3695652
If we subtract 276 from 300, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 16:
If we divide 240 by 138, we get 1 and a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 610157.36956521
Subtracting 138 from 240 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 610157.36956521 with a remaining 1.02e-07.
