Let's divide 91191001 by 673
We want to figure out the number of times 91191001 can be divided by 673.

Step 1:
673 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 673

Let's proceed to step 2:
The number 673 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Grab the next digit (1) from the dividend, add it to 91, then carry on: 911 / 673

On to step 3:
When dividing 911 by 673, we get 1 with a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 238 after subtracting 673 from 911.
Bring next digit (9) of the dividend behind the 238 and repeat the process: 2389 / 673

Going ahead to step 4:
If we divide 2389 by 673, we get 3 and a remainder of 370.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 2019 from 2389, we get 370.
Bring next digit (1) of the dividend behind the 370 and repeat the process: 3701 / 673

Advancing to step 5:
The number 673 fits into 3701 5 times, leaving a remainder of 336.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtracting 3365 from 3701 leaves us with 336.
Include the next digit (0) from the dividend after 336, then repeat: 3360 / 673

Going ahead to step 6:
3360 divided by 673 is 4 with a remainder of 668.
Put 4 as the next digit of the answer. 
Result so far: 1354.0
Subtract 2692 from 3360 to get 668.
Fetch the next digit (0) from the dividend, attach it to 668 and continue: 6680 / 673

Let's proceed to step 7:
6680 divided by 673 is 9 with a remainder of 623.
The next digit of our result is 9. 
Result so far: 13549.0
Deduct 6057 from 6680 and we're left with 623.
Bring next digit (1) of the dividend behind the 623 and repeat the process: 6231 / 673

Advancing to step 8:
The number 673 fits into 6231 9 times, leaving a remainder of 174.
Use 9 as the next digit of our solution. 
Result so far: 135499.0
Subtract 6057 from 6231 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
When dividing 1740 by 673, we get 2 with a remainder of 394.
Write down 2 as next digit of the result. 
Result so far: 135499.2
The remainder is 394 after subtracting 1346 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 10:
673 goes into 3940 5 times with a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 135499.25
If we take 3365 away from 3940, we end up with 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 11:
673 can be fit into 5750 8 times, resulting in a remainder of 366.
Use 8 as the next digit of our solution. 
Result so far: 135499.258
Subtract 5384 from 5750 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 12:
673 goes into 3660 5 times with a remainder of 295.
The next digit of our result is 5. 
Result so far: 135499.2585
Deduct 3365 from 3660 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 13:
673 goes into 2950 4 times with a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 135499.25854
Deduct 2692 from 2950 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 14:
If we divide 2580 by 673, we get 3 and a remainder of 561.
The next digit of our result is 3. 
Result so far: 135499.258543
The remainder is 561 after subtracting 2019 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Moving on to step 15:
When dividing 5610 by 673, we get 8 with a remainder of 226.
The next digit of our result is 8. 
Result so far: 135499.2585438
Deduct 5384 from 5610 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 16:
673 goes into 2260 3 times with a remainder of 241.
Put 3 as the next digit of the answer. 
Result so far: 135499.25854383
If we take 2019 away from 2260, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

After the division, we end up with 135499.25854383 and a remainder of 2.41e-07.
