We're dividing 63969195 by 138 
Our goal is to divide 63969195 by 138.

Advancing to step 1:
138 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 138

Let's proceed to step 2:
When dividing 63 by 138, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 138

Step 3:
The number 138 fits into 639 4 times, leaving a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 87 after subtracting 552 from 639.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 138

Advancing to step 4:
The number 138 fits into 876 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 828 from 876 to get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 138

Advancing to step 5:
The number 138 fits into 489 3 times, leaving a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 463.0
Subtracting 414 from 489 leaves us with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 138

On to step 6:
If we divide 751 by 138, we get 5 and a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 4635.0
Subtract 690 from 751 to get 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 138

On to step 7:
619 divided by 138 is 4 with a remainder of 67.
The next digit of our result is 4. 
Result so far: 46354.0
Subtract 552 from 619 to get 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 138

Going ahead to step 8:
138 goes into 675 4 times with a remainder of 123.
Use 4 as the next digit of our solution. 
Result so far: 463544.0
If we take 552 away from 675, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
If we divide 1230 by 138, we get 8 and a remainder of 126.
Record the quotient 8 as the next digit in the result. 
Result so far: 463544.8
Subtracting 1104 from 1230 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 10:
138 goes into 1260 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 463544.89
Deduct 1242 from 1260 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 11:
138 goes into 180 1 times with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 463544.891
Subtracting 138 from 180 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
138 can be fit into 420 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 463544.8913
If we take 414 away from 420, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
60 divided by 138 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 463544.8913
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.

Going ahead to step 14:
If we divide 600 by 138, we get 4 and a remainder of 48.
The next digit of our result is 4. 
Result so far: 463544.891304
Deduct 552 from 600 and we're left 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 15:
138 goes into 480 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 463544.8913043
If we take 414 away from 480, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 16:
138 can be fit into 660 4 times, resulting in a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 463544.89130434
If we subtract 552 from 660, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 463544.89130434 with a remainder of 1.08e-07.
