87993433 ÷ 193 
We want to figure out the number of times 87993433 can be divided by 193.

On to step 1:
The number 193 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 193

Step 2:
87 divided by 193 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 193

Step 3:
879 divided by 193 is 4 with a remainder of 107.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 772 from 879 leaves us with 107.
Grab the next digit (9) from the dividend, add it to 107, then carry on: 1079 / 193

Going ahead to step 4:
The number 193 fits into 1079 5 times, leaving a remainder of 114.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 965 away from 1079, we end up with 114.
Append the next digit (3) from the dividend to 114 and continue with: 1143 / 193

Let's proceed to step 5:
When dividing 1143 by 193, we get 5 with a remainder of 178.
Write down 5 as next digit of the result. 
Result so far: 455.0
The remainder is 178 after subtracting 965 from 1143.
Include the next digit (4) from the dividend after 178, then repeat: 1784 / 193

On to step 6:
The number 193 fits into 1784 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 4559.0
Subtract 1737 from 1784 to get 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 193

Advancing to step 7:
473 divided by 193 is 2 with a remainder of 87.
Use 2 as the next digit of our solution. 
Result so far: 45592.0
Deduct 386 from 473 and we're left with 87.
Append the next digit (3) from the dividend to 87 and continue with: 873 / 193

On to step 8:
193 can be fit into 873 4 times, resulting in a remainder of 101.
Use 4 as the next digit of our solution. 
Result so far: 455924.0
If we take 772 away from 873, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
If we divide 1010 by 193, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 455924.5
If we take 965 away from 1010, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
When dividing 450 by 193, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 455924.52
If we take 386 away from 450, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
193 can be fit into 640 3 times, resulting in a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 455924.523
The remainder is 61 after subtracting 579 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
610 divided by 193 is 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 455924.5233
Subtracting 579 from 610 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 455924.5233, and the remainder is 0.00031.
