Let's divide 17661871 by 258
We're looking to find how many times 258 goes into 17661871.

On to step 1:
1 divided by 258 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 258

Step 2:
If we divide 17 by 258, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 258

Step 3:
If we divide 176 by 258, we get 0 and a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 176 leaves us with 176.
Fetch the next digit (6) from the dividend, attach it to 176 and continue: 1766 / 258

Step 4:
The number 258 fits into 1766 6 times, leaving a remainder of 218.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 218 after subtracting 1548 from 1766.
Append the next digit (1) from the dividend to 218 and continue with: 2181 / 258

Going ahead to step 5:
258 can be fit into 2181 8 times, resulting in a remainder of 117.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 2064 from 2181, we get 117.
Grab the next digit (8) from the dividend, add it to 117, then carry on: 1178 / 258

On to step 6:
The number 258 fits into 1178 4 times, leaving a remainder of 146.
The next digit of our result is 4. 
Result so far: 684.0
If we subtract 1032 from 1178, we get 146.
Grab the next digit (7) from the dividend, add it to 146, then carry on: 1467 / 258

Moving on to step 7:
1467 divided by 258 is 5 with a remainder of 177.
Put 5 as the next digit of the answer. 
Result so far: 6845.0
Subtracting 1290 from 1467 leaves us with 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 258

Advancing to step 8:
258 goes into 1771 6 times with a remainder of 223.
Record the quotient 6 as the next digit in the result. 
Result so far: 68456.0
Deduct 1548 from 1771 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 9:
258 goes into 2230 8 times with a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 68456.8
Deduct 2064 from 2230 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 10:
The number 258 fits into 1660 6 times, leaving a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 68456.86
Deduct 1548 from 1660 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
When dividing 1120 by 258, we get 4 with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 68456.864
Deduct 1032 from 1120 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
258 can be fit into 880 3 times, resulting in a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 68456.8643
Subtracting 774 from 880 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 13:
If we divide 1060 by 258, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 68456.86434
Subtract 1032 from 1060 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
The number 258 fits into 280 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 68456.864341
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 15:
The number 258 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 68456.864341
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 16:
When dividing 2200 by 258, we get 8 with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 68456.86434108
Deduct 2064 from 2200 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 68456.86434108, with a leftover of 1.36e-07.
