We divide 72131993 by 152
We want to figure out the number of times 72131993 can be divided by 152.

Let's proceed to step 1:
152 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 152

On to step 2:
152 can be fit into 72 0 times, resulting in a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 152

Going ahead to step 3:
152 goes into 721 4 times with a remainder of 113.
The next digit of our result is 4. 
Result so far: 4.0
If we take 608 away from 721, we end up with 113.
Bring next digit (3) of the dividend behind the 113 and repeat the process: 1133 / 152

Advancing to step 4:
When dividing 1133 by 152, we get 7 with a remainder of 69.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 1064 from 1133 and we're left with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 152

On to step 5:
The number 152 fits into 691 4 times, leaving a remainder of 83.
The next digit of our result is 4. 
Result so far: 474.0
Deduct 608 from 691 and we're left with 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 152

Step 6:
839 divided by 152 is 5 with a remainder of 79.
Use 5 as the next digit of our solution. 
Result so far: 4745.0
Subtract 760 from 839 to get 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 152

Let's proceed to step 7:
The number 152 fits into 799 5 times, leaving a remainder of 39.
The next digit of our result is 5. 
Result so far: 47455.0
If we subtract 760 from 799, we get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 152

Step 8:
When dividing 393 by 152, we get 2 with a remainder of 89.
The number 2 becomes the next digit in our result. 
Result so far: 474552.0
The remainder is 89 after subtracting 304 from 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
The number 152 fits into 890 5 times, leaving a remainder of 130.
The next digit of our result is 5. 
Result so far: 474552.5
If we subtract 760 from 890, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
If we divide 1300 by 152, we get 8 and a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 474552.58
If we take 1216 away from 1300, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
152 goes into 840 5 times with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 474552.585
If we take 760 away from 840, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
If we divide 800 by 152, we get 5 and a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 474552.5855
Subtract 760 from 800 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 474552.5855, with a leftover of 0.0004.
