Let's divide 64431567 by 123
Our goal is to divide 64431567 by 123.

Let's proceed to step 1:
The number 123 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 123

Let's proceed to step 2:
When dividing 64 by 123, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 123

Moving on to step 3:
The number 123 fits into 644 5 times, leaving a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 615 from 644 to get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 123

Moving on to step 4:
The number 123 fits into 293 2 times, leaving a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 47 after subtracting 246 from 293.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 123

Advancing to step 5:
If we divide 471 by 123, we get 3 and a remainder of 102.
Record the quotient 3 as the next digit in the result. 
Result so far: 523.0
Deduct 369 from 471 and we're left with 102.
Include the next digit (5) from the dividend after 102, then repeat: 1025 / 123

Going ahead to step 6:
1025 divided by 123 is 8 with a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 5238.0
Subtracting 984 from 1025 leaves us with 41.
Bring next digit (6) of the dividend behind the 41 and repeat the process: 416 / 123

Step 7:
If we divide 416 by 123, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 52383.0
Subtracting 369 from 416 leaves us with 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 123

Let's proceed to step 8:
123 can be fit into 477 3 times, resulting in a remainder of 108.
Use 3 as the next digit of our solution. 
Result so far: 523833.0
Subtract 369 from 477 to 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.

Advancing to step 9:
123 can be fit into 1080 8 times, resulting in a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 523833.8
If we take 984 away from 1080, we end up 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.

Going ahead to step 10:
If we divide 960 by 123, we get 7 and a remainder of 99.
Record the quotient 7 as the next digit in the result. 
Result so far: 523833.87
The remainder is 99 after subtracting 861 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 11:
123 goes into 990 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 523833.878
Subtracting 984 from 990 leaves us 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.

Let's proceed to step 12:
If we divide 60 by 123, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 523833.878
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
The number 123 fits into 600 4 times, leaving a remainder of 108.
The next digit of our result is 4. 
Result so far: 523833.87804
Deduct 492 from 600 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 14:
The number 123 fits into 1080 8 times, leaving a remainder of 96.
The next digit of our result is 8. 
Result so far: 523833.878048
If we subtract 984 from 1080, we 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 15:
The number 123 fits into 960 7 times, leaving a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 523833.8780487
Deduct 861 from 960 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 16:
990 divided by 123 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 523833.87804878
Subtracting 984 from 990 leaves us 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.

The quotient of the division is 523833.87804878, and the remainder is 6e-09.
