We divide 81889761 by 258
We're looking to find how many times 258 goes into 81889761.

Let's proceed to step 1:
The number 258 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 258

Moving on to step 2:
If we divide 81 by 258, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 258

Advancing to step 3:
If we divide 818 by 258, we get 3 and a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 774 from 818 and we're left with 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 258

Moving on to step 4:
258 goes into 448 1 times with a remainder of 190.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we subtract 258 from 448, we get 190.
Include the next digit (9) from the dividend after 190, then repeat: 1909 / 258

Moving on to step 5:
When dividing 1909 by 258, we get 7 with a remainder of 103.
The next digit of our result is 7. 
Result so far: 317.0
The remainder is 103 after subtracting 1806 from 1909.
Take the next digit (7) from the dividend and append it to 103, then repeat: 1037 / 258

On to step 6:
1037 divided by 258 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 3174.0
If we subtract 1032 from 1037, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 258

Step 7:
56 divided by 258 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 31740.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (1) from the dividend, attach it to 56 and continue: 561 / 258

Going ahead to step 8:
The number 258 fits into 561 2 times, leaving a remainder of 45.
Use 2 as the next digit of our solution. 
Result so far: 317402.0
Subtract 516 from 561 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 9:
258 goes into 450 1 times with a remainder of 192.
Record the quotient 1 as the next digit in the result. 
Result so far: 317402.1
Deduct 258 from 450 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
258 goes into 1920 7 times with a remainder of 114.
Write down 7 as next digit of the result. 
Result so far: 317402.17
If we subtract 1806 from 1920, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
258 can be fit into 1140 4 times, resulting in a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 317402.174
The remainder is 108 after subtracting 1032 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 12:
The number 258 fits into 1080 4 times, leaving a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 317402.1744
Subtracting 1032 from 1080 leaves us 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 317402.1744 and a remainder of 0.00048.
