170686 divided by 58 
Let's see how many times 58 fits into 170686.

Going ahead to step 1:
The number 58 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 58

On to step 2:
When dividing 17 by 58, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 58

Going ahead to step 3:
58 goes into 170 2 times with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 116 from 170 leaves us with 54.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 58

On to step 4:
If we divide 546 by 58, we get 9 and a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 522 from 546, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 58

On to step 5:
58 goes into 248 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 294.0
Subtract 232 from 248 to get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 58

Moving on to step 6:
The number 58 fits into 166 2 times, leaving a remainder of 50.
The next digit of our result is 2. 
Result so far: 2942.0
Subtracting 116 from 166 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
58 can be fit into 500 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 2942.8
Deduct 464 from 500 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
360 divided by 58 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2942.86
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 58 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2942.862
Subtract 116 from 120 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
58 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2942.862
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 58, we get 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 2942.86206
Deduct 348 from 400 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
The number 58 fits into 520 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 2942.862068
If we take 464 away from 520, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
58 goes into 560 9 times with a remainder of 38.
The next digit of our result is 9. 
Result so far: 2942.8620689
Deduct 522 from 560 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
58 can be fit into 380 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 2942.86206896
Subtract 348 from 380 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 2942.86206896, with a leftover of 3.2e-08.
