We're dividing 64236705 by 138 
We want to divide 64236705 by 138.

Step 1:
138 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 138

Let's proceed to step 2:
138 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 138

On to step 3:
The number 138 fits into 642 4 times, leaving a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 90 after subtracting 552 from 642.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 138

Advancing to step 4:
If we divide 903 by 138, we get 6 and a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 828 away from 903, we end up with 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 138

Going ahead to step 5:
138 can be fit into 756 5 times, resulting in a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 465.0
Subtract 690 from 756 to get 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 138

On to step 6:
The number 138 fits into 667 4 times, leaving a remainder of 115.
Write down 4 as next digit of the result. 
Result so far: 4654.0
The remainder is 115 after subtracting 552 from 667.
Bring next digit (0) of the dividend behind the 115 and repeat the process: 1150 / 138

Advancing to step 7:
If we divide 1150 by 138, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 46548.0
Subtracting 1104 from 1150 leaves us with 46.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 138

Advancing to step 8:
If we divide 465 by 138, we get 3 and a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 465483.0
If we take 414 away from 465, we end up 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.
Record the quotient 3 as the next digit in the result. 
Result so far: 465483.3
Deduct 414 from 510 and we're left with 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:
If we divide 960 by 138, we get 6 and a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 465483.36
The remainder is 132 after subtracting 828 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
When dividing 1320 by 138, we get 9 with a remainder of 78.
Put 9 as the next digit of the answer. 
Result so far: 465483.369
Subtracting 1242 from 1320 leaves us with 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 goes into 780 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 465483.3695
The remainder is 90 after subtracting 690 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
138 can be fit into 900 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 465483.36956
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.

Let's proceed to step 14:
The number 138 fits into 720 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 465483.369565
Subtracting 690 from 720 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 15:
If we divide 300 by 138, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 465483.3695652
Subtract 276 from 300 to 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.

Step 16:
138 can be fit into 240 1 times, resulting in a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 465483.36956521
If we take 138 away from 240, we end up 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.

The final outcome is 465483.36956521, with a leftover of 1.02e-07.
