We're dividing 64386417 by 138 
Let's see how many times 138 fits into 64386417.

Going ahead to step 1:
6 divided by 138 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 138

On to step 2:
64 divided by 138 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Fetch the next digit (3) from the dividend, attach it to 64 and continue: 643 / 138

Moving on to step 3:
643 divided by 138 is 4 with a remainder of 91.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 552 away from 643, we end up with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 138

Step 4:
138 can be fit into 918 6 times, resulting in a remainder of 90.
The next digit of our result is 6. 
Result so far: 46.0
Deduct 828 from 918 and we're left with 90.
Bring next digit (6) of the dividend behind the 90 and repeat the process: 906 / 138

Going ahead to step 5:
906 divided by 138 is 6 with a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 466.0
If we take 828 away from 906, we end up with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 138

Going ahead to step 6:
138 can be fit into 784 5 times, resulting in a remainder of 94.
The number 5 becomes the next digit in our result. 
Result so far: 4665.0
If we take 690 away from 784, we end up with 94.
Append the next digit (1) from the dividend to 94 and continue with: 941 / 138

Going ahead to step 7:
941 divided by 138 is 6 with a remainder of 113.
The number 6 becomes the next digit in our result. 
Result so far: 46656.0
Subtract 828 from 941 to get 113.
Take the next digit (7) from the dividend and append it to 113, then repeat: 1137 / 138

Step 8:
When dividing 1137 by 138, we get 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 466568.0
The remainder is 33 after subtracting 1104 from 1137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
138 can be fit into 330 2 times, resulting in a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 466568.2
Subtract 276 from 330 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
If we divide 540 by 138, we get 3 and a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 466568.23
If we subtract 414 from 540, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 11:
If we divide 1260 by 138, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 466568.239
If we subtract 1242 from 1260, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
The number 138 fits into 180 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 466568.2391
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.

Step 13:
The number 138 fits into 420 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 466568.23913
If we subtract 414 from 420, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
60 divided by 138 is 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 466568.23913
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
When dividing 600 by 138, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 466568.2391304
If we take 552 away from 600, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 16:
480 divided by 138 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 466568.23913043
If we subtract 414 from 480, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 466568.23913043, with a leftover of 6.6e-08.
