16121104 divided by 673 
We want to figure out the number of times 16121104 can be divided by 673.

On to step 1:
1 divided by 673 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 673

On to step 2:
If we divide 16 by 673, we get 0 and a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 673

Let's proceed to step 3:
673 goes into 161 0 times with a remainder of 161.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 161, we end up with 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 673

Advancing to step 4:
1612 divided by 673 is 2 with a remainder of 266.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 266 after subtracting 1346 from 1612.
Fetch the next digit (1) from the dividend, attach it to 266 and continue: 2661 / 673

Let's proceed to step 5:
673 goes into 2661 3 times with a remainder of 642.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 2019 from 2661 and we're left with 642.
Fetch the next digit (1) from the dividend, attach it to 642 and continue: 6421 / 673

On to step 6:
673 goes into 6421 9 times with a remainder of 364.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtract 6057 from 6421 to get 364.
Append the next digit (0) from the dividend to 364 and continue with: 3640 / 673

Advancing to step 7:
3640 divided by 673 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 2395.0
The remainder is 275 after subtracting 3365 from 3640.
Fetch the next digit (4) from the dividend, attach it to 275 and continue: 2754 / 673

Moving on to step 8:
673 goes into 2754 4 times with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 23954.0
If we take 2692 away from 2754, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 9:
If we divide 620 by 673, we get 0 and a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 23954.0
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 10:
If we divide 6200 by 673, we get 9 and a remainder of 143.
The next digit of our result is 9. 
Result so far: 23954.09
If we take 6057 away from 6200, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 11:
If we divide 1430 by 673, we get 2 and a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 23954.092
The remainder is 84 after subtracting 1346 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 12:
When dividing 840 by 673, we get 1 with a remainder of 167.
Write down 1 as next digit of the result. 
Result so far: 23954.0921
If we take 673 away from 840, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 13:
If we divide 1670 by 673, we get 2 and a remainder of 324.
The next digit of our result is 2. 
Result so far: 23954.09212
Subtracting 1346 from 1670 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 14:
3240 divided by 673 is 4 with a remainder of 548.
The next digit of our result is 4. 
Result so far: 23954.092124
Subtract 2692 from 3240 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 15:
673 goes into 5480 8 times with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 23954.0921248
The remainder is 96 after subtracting 5384 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
The number 673 fits into 960 1 times, leaving a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 23954.09212481
Deduct 673 from 960 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

After the division, we end up with 23954.09212481 and a remainder of 2.87e-07.
