72105920 ÷ 193 
We want to figure out the number of times 72105920 can be divided by 193.

Moving on to step 1:
If we divide 7 by 193, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 193

Advancing to step 2:
When dividing 72 by 193, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 193

On to step 3:
193 can be fit into 721 3 times, resulting in a remainder of 142.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 142 after subtracting 579 from 721.
Append the next digit (0) from the dividend to 142 and continue with: 1420 / 193

Going ahead to step 4:
193 goes into 1420 7 times with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 1351 away from 1420, we end up with 69.
Grab the next digit (5) from the dividend, add it to 69, then carry on: 695 / 193

Moving on to step 5:
695 divided by 193 is 3 with a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
Subtracting 579 from 695 leaves us with 116.
Append the next digit (9) from the dividend to 116 and continue with: 1169 / 193

Moving on to step 6:
193 can be fit into 1169 6 times, resulting in a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 3736.0
Subtracting 1158 from 1169 leaves us with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 193

Going ahead to step 7:
When dividing 112 by 193, we get 0 with a remainder of 112.
Use 0 as the next digit of our solution. 
Result so far: 37360.0
If we take 0 away from 112, we end up with 112.
Include the next digit (0) from the dividend after 112, then repeat: 1120 / 193

Let's proceed to step 8:
193 goes into 1120 5 times with a remainder of 155.
The next digit of our result is 5. 
Result so far: 373605.0
If we subtract 965 from 1120, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 9:
193 can be fit into 1550 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 373605.8
Deduct 1544 from 1550 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 193 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 373605.8
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
The number 193 fits into 600 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 373605.803
The remainder is 21 after subtracting 579 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
When dividing 210 by 193, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 373605.8031
If we take 193 away from 210, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
193 can be fit into 170 0 times, resulting in a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 373605.8031
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 14:
193 can be fit into 1700 8 times, resulting in a remainder of 156.
Use 8 as the next digit of our solution. 
Result so far: 373605.803108
If we take 1544 away from 1700, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 15:
When dividing 1560 by 193, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 373605.8031088
If we subtract 1544 from 1560, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 373605.8031088, and the remainder is 1.6e-07.
