We divide 25135464 by 159
We want to figure out the number of times 25135464 can be divided by 159.

Advancing to step 1:
If we divide 2 by 159, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 159

On to step 2:
159 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 159

Moving on to step 3:
159 can be fit into 251 1 times, resulting in a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 159 from 251 leaves us with 92.
Take the next digit (3) from the dividend and append it to 92, then repeat: 923 / 159

Going ahead to step 4:
The number 159 fits into 923 5 times, leaving a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 795 from 923 to get 128.
Fetch the next digit (5) from the dividend, attach it to 128 and continue: 1285 / 159

Moving on to step 5:
The number 159 fits into 1285 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtract 1272 from 1285 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 159

Advancing to step 6:
The number 159 fits into 134 0 times, leaving a remainder of 134.
The number 0 becomes the next digit in our result. 
Result so far: 1580.0
Deduct 0 from 134 and we're left with 134.
Include the next digit (6) from the dividend after 134, then repeat: 1346 / 159

Let's proceed to step 7:
When dividing 1346 by 159, we get 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 15808.0
Deduct 1272 from 1346 and we're left with 74.
Grab the next digit (4) from the dividend, add it to 74, then carry on: 744 / 159

Let's proceed to step 8:
159 can be fit into 744 4 times, resulting in a remainder of 108.
Record the quotient 4 as the next digit in the result. 
Result so far: 158084.0
Subtract 636 from 744 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
If we divide 1080 by 159, we get 6 and a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 158084.6
Deduct 954 from 1080 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 10:
1260 divided by 159 is 7 with a remainder of 147.
Put 7 as the next digit of the answer. 
Result so far: 158084.67
The remainder is 147 after subtracting 1113 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 11:
159 goes into 1470 9 times with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 158084.679
The remainder is 39 after subtracting 1431 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 12:
390 divided by 159 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 158084.6792
If we take 318 away from 390, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
When dividing 720 by 159, we get 4 with a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 158084.67924
If we take 636 away from 720, 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.

Moving on to step 14:
When dividing 840 by 159, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 158084.679245
If we take 795 away from 840, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 15:
If we divide 450 by 159, we get 2 and a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 158084.6792452
Subtracting 318 from 450 leaves us 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.

Advancing to step 16:
When dividing 1320 by 159, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 158084.67924528
If we take 1272 away from 1320, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 158084.67924528 and a remainder of 4.8e-08.
