We divide 25148931 by 170
Our goal is to divide 25148931 by 170.

Advancing to step 1:
The number 170 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 170

Let's proceed to step 2:
When dividing 25 by 170, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 170

Moving on to step 3:
The number 170 fits into 251 1 times, leaving a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 81 after subtracting 170 from 251.
Fetch the next digit (4) from the dividend, attach it to 81 and continue: 814 / 170

Going ahead to step 4:
When dividing 814 by 170, we get 4 with a remainder of 134.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 680 away from 814, we end up with 134.
Append the next digit (8) from the dividend to 134 and continue with: 1348 / 170

Step 5:
170 can be fit into 1348 7 times, resulting in a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 147.0
The remainder is 158 after subtracting 1190 from 1348.
Append the next digit (9) from the dividend to 158 and continue with: 1589 / 170

Let's proceed to step 6:
170 goes into 1589 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 1479.0
If we take 1530 away from 1589, we end up with 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 170

On to step 7:
If we divide 593 by 170, we get 3 and a remainder of 83.
The number 3 becomes the next digit in our result. 
Result so far: 14793.0
Subtract 510 from 593 to get 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 170

Going ahead to step 8:
The number 170 fits into 831 4 times, leaving a remainder of 151.
The next digit of our result is 4. 
Result so far: 147934.0
If we take 680 away from 831, we end up 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.

Going ahead to step 9:
The number 170 fits into 1510 8 times, leaving a remainder of 150.
The number 8 becomes the next digit in our result. 
Result so far: 147934.8
Subtract 1360 from 1510 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 10:
If we divide 1500 by 170, we get 8 and a remainder of 140.
The number 8 becomes the next digit in our result. 
Result so far: 147934.88
The remainder is 140 after subtracting 1360 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 147934.88, and the remainder is 0.14.
