73673015 ÷ 631 
Our goal is to divide 73673015 by 631.

On to step 1:
If we divide 7 by 631, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 631

Advancing to step 2:
631 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Fetch the next digit (6) from the dividend, attach it to 73 and continue: 736 / 631

On to step 3:
The number 631 fits into 736 1 times, leaving a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 631 from 736, we get 105.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 631

Moving on to step 4:
When dividing 1057 by 631, we get 1 with a remainder of 426.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 426 after subtracting 631 from 1057.
Include the next digit (3) from the dividend after 426, then repeat: 4263 / 631

On to step 5:
631 goes into 4263 6 times with a remainder of 477.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Deduct 3786 from 4263 and we're left with 477.
Take the next digit (0) from the dividend and append it to 477, then repeat: 4770 / 631

Step 6:
If we divide 4770 by 631, we get 7 and a remainder of 353.
Write down 7 as next digit of the result. 
Result so far: 1167.0
If we subtract 4417 from 4770, we get 353.
Include the next digit (1) from the dividend after 353, then repeat: 3531 / 631

Moving on to step 7:
If we divide 3531 by 631, we get 5 and a remainder of 376.
Record the quotient 5 as the next digit in the result. 
Result so far: 11675.0
If we subtract 3155 from 3531, we get 376.
Grab the next digit (5) from the dividend, add it to 376, then carry on: 3765 / 631

Let's proceed to step 8:
631 goes into 3765 5 times with a remainder of 610.
Put 5 as the next digit of the answer. 
Result so far: 116755.0
If we take 3155 away from 3765, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 9:
6100 divided by 631 is 9 with a remainder of 421.
Use 9 as the next digit of our solution. 
Result so far: 116755.9
If we subtract 5679 from 6100, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

On to step 10:
4210 divided by 631 is 6 with a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 116755.96
If we take 3786 away from 4210, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
The number 631 fits into 4240 6 times, leaving a remainder of 454.
Write down 6 as next digit of the result. 
Result so far: 116755.966
If we subtract 3786 from 4240, 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.

In conclusion, the division gives 116755.966 with a balance of 0.0454.
