25715393 ÷ 161 
We're looking to find how many times 161 goes into 25715393.

On to step 1:
161 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 161

On to step 2:
If we divide 25 by 161, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 161

Step 3:
The number 161 fits into 257 1 times, leaving a remainder of 96.
The next digit of our result is 1. 
Result so far: 1.0
If we take 161 away from 257, we end up with 96.
Include the next digit (1) from the dividend after 96, then repeat: 961 / 161

On to step 4:
When dividing 961 by 161, we get 5 with a remainder of 156.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 156 after subtracting 805 from 961.
Fetch the next digit (5) from the dividend, attach it to 156 and continue: 1565 / 161

Moving on to step 5:
The number 161 fits into 1565 9 times, leaving a remainder of 116.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we take 1449 away from 1565, we end up with 116.
Append the next digit (3) from the dividend to 116 and continue with: 1163 / 161

Let's proceed to step 6:
161 can be fit into 1163 7 times, resulting in a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 1597.0
Subtracting 1127 from 1163 leaves us with 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 161

Going ahead to step 7:
When dividing 369 by 161, we get 2 with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 15972.0
If we subtract 322 from 369, we get 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 161

Step 8:
The number 161 fits into 473 2 times, leaving a remainder of 151.
Use 2 as the next digit of our solution. 
Result so far: 159722.0
Subtracting 322 from 473 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 9:
161 goes into 1510 9 times with a remainder of 61.
The next digit of our result is 9. 
Result so far: 159722.9
The remainder is 61 after subtracting 1449 from 1510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 10:
161 goes into 610 3 times with a remainder of 127.
Write down 3 as next digit of the result. 
Result so far: 159722.93
If we take 483 away from 610, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 11:
When dividing 1270 by 161, we get 7 with a remainder of 143.
The number 7 becomes the next digit in our result. 
Result so far: 159722.937
The remainder is 143 after subtracting 1127 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 12:
When dividing 1430 by 161, we get 8 with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 159722.9378
Deduct 1288 from 1430 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 13:
161 can be fit into 1420 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 159722.93788
If we take 1288 away from 1420, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 159722.93788 with a remainder of 0.000132.
