64139739 ÷ 193 
Our goal is to divide 64139739 by 193.

On to step 1:
193 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 193

Advancing to step 2:
193 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 193

Moving on to step 3:
The number 193 fits into 641 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 579 from 641 leaves us with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 193

Advancing to step 4:
When dividing 623 by 193, we get 3 with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 579 from 623, we get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 193

Going ahead to step 5:
When dividing 449 by 193, we get 2 with a remainder of 63.
Record the quotient 2 as the next digit in the result. 
Result so far: 332.0
Subtracting 386 from 449 leaves us with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 193

Step 6:
193 can be fit into 637 3 times, resulting in a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 3323.0
Subtract 579 from 637 to get 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 193

Advancing to step 7:
The number 193 fits into 583 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 33233.0
If we subtract 579 from 583, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 193

Let's proceed to step 8:
The number 193 fits into 49 0 times, leaving a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 332330.0
Subtracting 0 from 49 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
490 divided by 193 is 2 with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 332330.2
The remainder is 104 after subtracting 386 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 10:
193 goes into 1040 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 332330.25
The remainder is 75 after subtracting 965 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
193 goes into 750 3 times with a remainder of 171.
Put 3 as the next digit of the answer. 
Result so far: 332330.253
If we subtract 579 from 750, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Moving on to step 12:
193 can be fit into 1710 8 times, resulting in a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 332330.2538
If we take 1544 away from 1710, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 13:
1660 divided by 193 is 8 with a remainder of 116.
The next digit of our result is 8. 
Result so far: 332330.25388
The remainder is 116 after subtracting 1544 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 332330.25388, and the remainder is 0.000116.
