We divide 521542 by 91
We're looking to find how many times 91 goes into 521542.

On to step 1:
91 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 91

On to step 2:
The number 91 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 91

Advancing to step 3:
If we divide 521 by 91, we get 5 and a remainder of 66.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 455 from 521 and we're left with 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 91

On to step 4:
If we divide 665 by 91, we get 7 and a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Deduct 637 from 665 and we're left with 28.
Fetch the next digit (4) from the dividend, attach it to 28 and continue: 284 / 91

Advancing to step 5:
91 goes into 284 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 573.0
Subtracting 273 from 284 leaves us with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 91

Advancing to step 6:
91 goes into 112 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 5731.0
Subtracting 91 from 112 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
If we divide 210 by 91, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 5731.2
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.

Step 8:
91 can be fit into 280 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 5731.23
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.

Let's proceed to step 9:
70 divided by 91 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 5731.23
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.

Let's proceed to step 10:
91 can be fit into 700 7 times, resulting in a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 5731.2307
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.

Step 11:
The number 91 fits into 630 6 times, leaving a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 5731.23076
The remainder is 84 after subtracting 546 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
When dividing 840 by 91, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 5731.230769
If we take 819 away from 840, we end up with 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 13:
210 divided by 91 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 5731.2307692
Subtract 182 from 210 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.

Going ahead to step 14:
When dividing 280 by 91, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 5731.23076923
Deduct 273 from 280 and we're left with 7.
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 5731.23076923 with a balance of 7e-09.
