46949603 ÷ 123 
Let's see how many times 123 fits into 46949603.

Advancing to step 1:
If we divide 4 by 123, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 123

Advancing to step 2:
46 divided by 123 is 0 with a remainder of 46.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 123

Advancing to step 3:
123 can be fit into 469 3 times, resulting in a remainder of 100.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 369 from 469 and we're left with 100.
Take the next digit (4) from the dividend and append it to 100, then repeat: 1004 / 123

Step 4:
If we divide 1004 by 123, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 984 from 1004 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 123

Going ahead to step 5:
209 divided by 123 is 1 with a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 381.0
Subtract 123 from 209 to get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 123

Going ahead to step 6:
When dividing 866 by 123, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 3817.0
If we subtract 861 from 866, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 123

Let's proceed to step 7:
50 divided by 123 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 38170.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 123

Moving on to step 8:
When dividing 503 by 123, we get 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 381704.0
If we take 492 away from 503, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
If we divide 110 by 123, we get 0 and a remainder of 110.
The next digit of our result is 0. 
Result so far: 381704.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
123 goes into 1100 8 times with a remainder of 116.
The next digit of our result is 8. 
Result so far: 381704.08
The remainder is 116 after subtracting 984 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
When dividing 1160 by 123, we get 9 with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 381704.089
Deduct 1107 from 1160 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 12:
530 divided by 123 is 4 with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 381704.0894
Subtracting 492 from 530 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
123 can be fit into 380 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 381704.08943
Subtracting 369 from 380 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
110 divided by 123 is 0 with a remainder of 110.
The next digit of our result is 0. 
Result so far: 381704.08943
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 15:
If we divide 1100 by 123, we get 8 and a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 381704.0894308
The remainder is 116 after subtracting 984 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 16:
When dividing 1160 by 123, we get 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 381704.08943089
The remainder is 53 after subtracting 1107 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

In conclusion, the division gives 381704.08943089 with a balance of 5.3e-08.
