We're dividing 46407631 by 663 
Let's see how many times 663 fits into 46407631.

Advancing to step 1:
If we divide 4 by 663, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 663

On to step 2:
If we divide 46 by 663, we get 0 and a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 663

Moving on to step 3:
663 goes into 464 0 times with a remainder of 464.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 464 after subtracting 0 from 464.
Append the next digit (0) from the dividend to 464 and continue with: 4640 / 663

Let's proceed to step 4:
4640 divided by 663 is 6 with a remainder of 662.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 662 after subtracting 3978 from 4640.
Grab the next digit (7) from the dividend, add it to 662, then carry on: 6627 / 663

Step 5:
When dividing 6627 by 663, we get 9 with a remainder of 660.
Write down 9 as next digit of the result. 
Result so far: 69.0
Deduct 5967 from 6627 and we're left with 660.
Grab the next digit (6) from the dividend, add it to 660, then carry on: 6606 / 663

Let's proceed to step 6:
6606 divided by 663 is 9 with a remainder of 639.
The next digit of our result is 9. 
Result so far: 699.0
Subtract 5967 from 6606 to get 639.
Include the next digit (3) from the dividend after 639, then repeat: 6393 / 663

Let's proceed to step 7:
When dividing 6393 by 663, we get 9 with a remainder of 426.
Put 9 as the next digit of the answer. 
Result so far: 6999.0
Subtracting 5967 from 6393 leaves us with 426.
Take the next digit (1) from the dividend and append it to 426, then repeat: 4261 / 663

Going ahead to step 8:
663 can be fit into 4261 6 times, resulting in a remainder of 283.
Record the quotient 6 as the next digit in the result. 
Result so far: 69996.0
Subtracting 3978 from 4261 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 9:
663 can be fit into 2830 4 times, resulting in a remainder of 178.
Put 4 as the next digit of the answer. 
Result so far: 69996.4
If we subtract 2652 from 2830, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 10:
When dividing 1780 by 663, we get 2 with a remainder of 454.
The next digit of our result is 2. 
Result so far: 69996.42
If we subtract 1326 from 1780, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 11:
When dividing 4540 by 663, we get 6 with a remainder of 562.
Record the quotient 6 as the next digit in the result. 
Result so far: 69996.426
Subtract 3978 from 4540 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 12:
The number 663 fits into 5620 8 times, leaving a remainder of 316.
The next digit of our result is 8. 
Result so far: 69996.4268
If we take 5304 away from 5620, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 13:
When dividing 3160 by 663, we get 4 with a remainder of 508.
Write down 4 as next digit of the result. 
Result so far: 69996.42684
Subtracting 2652 from 3160 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 14:
If we divide 5080 by 663, we get 7 and a remainder of 439.
The next digit of our result is 7. 
Result so far: 69996.426847
If we take 4641 away from 5080, we end up with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 15:
663 goes into 4390 6 times with a remainder of 412.
Use 6 as the next digit of our solution. 
Result so far: 69996.4268476
The remainder is 412 after subtracting 3978 from 4390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 16:
663 can be fit into 4120 6 times, resulting in a remainder of 142.
Use 6 as the next digit of our solution. 
Result so far: 69996.42684766
If we take 3978 away from 4120, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 69996.42684766 with a remainder of 1.42e-07.
