We look at the division of 46389666 by 123 
Let's see how many times 123 fits into 46389666.

Let's proceed to step 1:
The number 123 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 123

Let's proceed to step 2:
When dividing 46 by 123, we get 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 123

Let's proceed to step 3:
123 can be fit into 463 3 times, resulting in a remainder of 94.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 369 from 463 to get 94.
Bring next digit (8) of the dividend behind the 94 and repeat the process: 948 / 123

Let's proceed to step 4:
123 can be fit into 948 7 times, resulting in a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
Subtract 861 from 948 to get 87.
Include the next digit (9) from the dividend after 87, then repeat: 879 / 123

Let's proceed to step 5:
123 goes into 879 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 377.0
Subtracting 861 from 879 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 123

On to step 6:
The number 123 fits into 186 1 times, leaving a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 3771.0
Deduct 123 from 186 and we're left with 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 123

Advancing to step 7:
If we divide 636 by 123, we get 5 and a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 37715.0
Deduct 615 from 636 and we're left with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 123

Step 8:
When dividing 216 by 123, we get 1 with a remainder of 93.
Put 1 as the next digit of the answer. 
Result so far: 377151.0
Deduct 123 from 216 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 9:
123 goes into 930 7 times with a remainder of 69.
The next digit of our result is 7. 
Result so far: 377151.7
Deduct 861 from 930 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
The number 123 fits into 690 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 377151.75
Subtract 615 from 690 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
The number 123 fits into 750 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 377151.756
Subtracting 738 from 750 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 12:
When dividing 120 by 123, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 377151.756
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
123 can be fit into 1200 9 times, resulting in a remainder of 93.
Write down 9 as next digit of the result. 
Result so far: 377151.75609
Deduct 1107 from 1200 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 14:
When dividing 930 by 123, we get 7 with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 377151.756097
If we subtract 861 from 930, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 15:
If we divide 690 by 123, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 377151.7560975
If we take 615 away from 690, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 16:
750 divided by 123 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 377151.75609756
The remainder is 12 after subtracting 738 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 377151.75609756 with a remainder of 1.2e-08.
