391666 divided by 58 
We want to figure out the number of times 391666 can be divided by 58.

Advancing to step 1:
The number 58 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 58

Let's proceed to step 2:
39 divided by 58 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 58

On to step 3:
391 divided by 58 is 6 with a remainder of 43.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 348 from 391 to get 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 58

Going ahead to step 4:
58 goes into 436 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Deduct 406 from 436 and we're left with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 58

Let's proceed to step 5:
When dividing 306 by 58, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 675.0
If we take 290 away from 306, we end up with 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 58

Moving on to step 6:
If we divide 166 by 58, we get 2 and a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 6752.0
Subtract 116 from 166 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
If we divide 500 by 58, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 6752.8
Subtract 464 from 500 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
58 can be fit into 360 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 6752.86
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
58 goes into 120 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 6752.862
If we subtract 116 from 120, we 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.

Step 10:
When dividing 40 by 58, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 6752.862
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
If we divide 400 by 58, we get 6 and a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6752.86206
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
58 goes into 520 8 times with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 6752.862068
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.
Write down 9 as next digit of the result. 
Result so far: 6752.8620689
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
58 goes into 380 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 6752.86206896
If we take 348 away from 380, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 6752.86206896 with a remaining 3.2e-08.
