99710783 ÷ 673 
We want to figure out the number of times 99710783 can be divided by 673.

Let's proceed to step 1:
673 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 673

Let's proceed to step 2:
When dividing 99 by 673, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 673

On to step 3:
If we divide 997 by 673, we get 1 and a remainder of 324.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 324 after subtracting 673 from 997.
Include the next digit (1) from the dividend after 324, then repeat: 3241 / 673

Let's proceed to step 4:
If we divide 3241 by 673, we get 4 and a remainder of 549.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2692 from 3241, we get 549.
Include the next digit (0) from the dividend after 549, then repeat: 5490 / 673

On to step 5:
5490 divided by 673 is 8 with a remainder of 106.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we take 5384 away from 5490, we end up with 106.
Fetch the next digit (7) from the dividend, attach it to 106 and continue: 1067 / 673

Advancing to step 6:
The number 673 fits into 1067 1 times, leaving a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 1481.0
If we subtract 673 from 1067, we get 394.
Append the next digit (8) from the dividend to 394 and continue with: 3948 / 673

Step 7:
3948 divided by 673 is 5 with a remainder of 583.
Write down 5 as next digit of the result. 
Result so far: 14815.0
Deduct 3365 from 3948 and we're left with 583.
Fetch the next digit (3) from the dividend, attach it to 583 and continue: 5833 / 673

Let's proceed to step 8:
673 can be fit into 5833 8 times, resulting in a remainder of 449.
Write down 8 as next digit of the result. 
Result so far: 148158.0
Subtracting 5384 from 5833 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead to step 9:
4490 divided by 673 is 6 with a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 148158.6
Deduct 4038 from 4490 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 10:
When dividing 4520 by 673, we get 6 with a remainder of 482.
The next digit of our result is 6. 
Result so far: 148158.66
Subtract 4038 from 4520 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

The final outcome is 148158.66, with a leftover of 0.482.
