Let's divide 573958 by 91
We want to figure out the number of times 573958 can be divided by 91.

Going ahead to step 1:
91 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 91

Advancing to step 2:
The number 91 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Append the next digit (3) from the dividend to 57 and continue with: 573 / 91

Step 3:
573 divided by 91 is 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 546 from 573 leaves us with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 91

Let's proceed to step 4:
If we divide 279 by 91, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 273 from 279, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 91

Going ahead to step 5:
91 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 630.0
Deduct 0 from 65 and we're left with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 91

Going ahead to step 6:
91 can be fit into 658 7 times, resulting in a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 6307.0
If we subtract 637 from 658, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 91, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6307.2
The remainder is 28 after subtracting 182 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
When dividing 280 by 91, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 6307.23
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
When dividing 70 by 91, we get 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 6307.23
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
When dividing 700 by 91, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 6307.2307
The remainder is 63 after subtracting 637 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 11:
If we divide 630 by 91, we get 6 and a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 6307.23076
Deduct 546 from 630 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
91 can be fit into 840 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 6307.230769
If we subtract 819 from 840, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
When dividing 210 by 91, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 6307.2307692
Deduct 182 from 210 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 14:
The number 91 fits into 280 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 6307.23076923
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 6307.23076923 with a balance of 7e-09.
