We look at the division of 96133191 by 643 
Let's see how many times 643 fits into 96133191.

Let's proceed to step 1:
643 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 subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 643

Advancing to step 2:
When dividing 96 by 643, we get 0 with a remainder of 96.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 96 and we're left with 96.
Take the next digit (1) from the dividend and append it to 96, then repeat: 961 / 643

Advancing to step 3:
643 can be fit into 961 1 times, resulting in a remainder of 318.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 643 from 961 leaves us with 318.
Include the next digit (3) from the dividend after 318, then repeat: 3183 / 643

Moving on to step 4:
643 goes into 3183 4 times with a remainder of 611.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2572 from 3183, we get 611.
Take the next digit (3) from the dividend and append it to 611, then repeat: 6113 / 643

Moving on to step 5:
The number 643 fits into 6113 9 times, leaving a remainder of 326.
The next digit of our result is 9. 
Result so far: 149.0
Deduct 5787 from 6113 and we're left with 326.
Grab the next digit (1) from the dividend, add it to 326, then carry on: 3261 / 643

On to step 6:
The number 643 fits into 3261 5 times, leaving a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 1495.0
If we take 3215 away from 3261, we end up with 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 643

Going ahead to step 7:
643 can be fit into 469 0 times, resulting in a remainder of 469.
Use 0 as the next digit of our solution. 
Result so far: 14950.0
Subtract 0 from 469 to get 469.
Bring next digit (1) of the dividend behind the 469 and repeat the process: 4691 / 643

Let's proceed to step 8:
If we divide 4691 by 643, we get 7 and a remainder of 190.
The next digit of our result is 7. 
Result so far: 149507.0
Subtracting 4501 from 4691 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
The number 643 fits into 1900 2 times, leaving a remainder of 614.
Use 2 as the next digit of our solution. 
Result so far: 149507.2
If we take 1286 away from 1900, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 10:
When dividing 6140 by 643, we get 9 with a remainder of 353.
Use 9 as the next digit of our solution. 
Result so far: 149507.29
Subtract 5787 from 6140 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Going ahead to step 11:
If we divide 3530 by 643, we get 5 and a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 149507.295
Subtract 3215 from 3530 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 12:
The number 643 fits into 3150 4 times, leaving a remainder of 578.
Put 4 as the next digit of the answer. 
Result so far: 149507.2954
Deduct 2572 from 3150 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 13:
5780 divided by 643 is 8 with a remainder of 636.
The next digit of our result is 8. 
Result so far: 149507.29548
If we take 5144 away from 5780, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 14:
643 goes into 6360 9 times with a remainder of 573.
Write down 9 as next digit of the result. 
Result so far: 149507.295489
Subtracting 5787 from 6360 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Moving on to step 15:
643 can be fit into 5730 8 times, resulting in a remainder of 586.
The next digit of our result is 8. 
Result so far: 149507.2954898
Deduct 5144 from 5730 and we're left with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 16:
5860 divided by 643 is 9 with a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 149507.29548989
Subtracting 5787 from 5860 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final outcome is 149507.29548989, with a leftover of 7.3e-08.
