We divide 72052139 by 161
We want to figure out the number of times 72052139 can be divided by 161.

Step 1:
When dividing 7 by 161, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 161

Moving on to step 2:
The number 161 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 161

Step 3:
The number 161 fits into 720 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 644 from 720 leaves us with 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 161

Advancing to step 4:
161 can be fit into 765 4 times, resulting in a remainder of 121.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we subtract 644 from 765, we get 121.
Grab the next digit (2) from the dividend, add it to 121, then carry on: 1212 / 161

Advancing to step 5:
161 goes into 1212 7 times with a remainder of 85.
Use 7 as the next digit of our solution. 
Result so far: 447.0
Subtract 1127 from 1212 to get 85.
Append the next digit (1) from the dividend to 85 and continue with: 851 / 161

Let's proceed to step 6:
161 goes into 851 5 times with a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 4475.0
If we take 805 away from 851, we end up with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 161

Let's proceed to step 7:
161 goes into 463 2 times with a remainder of 141.
Use 2 as the next digit of our solution. 
Result so far: 44752.0
If we take 322 away from 463, we end up with 141.
Grab the next digit (9) from the dividend, add it to 141, then carry on: 1419 / 161

Step 8:
1419 divided by 161 is 8 with a remainder of 131.
The number 8 becomes the next digit in our result. 
Result so far: 447528.0
Subtracting 1288 from 1419 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
If we divide 1310 by 161, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 447528.8
If we subtract 1288 from 1310, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
161 goes into 220 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 447528.81
The remainder is 59 after subtracting 161 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 11:
590 divided by 161 is 3 with a remainder of 107.
Put 3 as the next digit of the answer. 
Result so far: 447528.813
Subtracting 483 from 590 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 12:
If we divide 1070 by 161, we get 6 and a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 447528.8136
If we take 966 away from 1070, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
161 goes into 1040 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 447528.81366
If we subtract 966 from 1040, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 447528.81366 and a remainder of 7.4e-05.
