We look at the division of 521767 by 91 
Let's see how many times 91 fits into 521767.

On to step 1:
91 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 91

Step 2:
91 goes into 52 0 times with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 91

Moving on to step 3:
If we divide 521 by 91, we get 5 and a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 66 after subtracting 455 from 521.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 91

On to step 4:
If we divide 667 by 91, we get 7 and a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 57.0
If we take 637 away from 667, we end up with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 91

Step 5:
306 divided by 91 is 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 573.0
If we take 273 away from 306, we end up with 33.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 91

Let's proceed to step 6:
The number 91 fits into 337 3 times, leaving a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 5733.0
If we take 273 away from 337, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
If we divide 640 by 91, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 5733.7
Subtracting 637 from 640 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
If we divide 30 by 91, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5733.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
When dividing 300 by 91, we get 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 5733.703
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
If we divide 270 by 91, we get 2 and a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 5733.7032
If we take 182 away from 270, we end up 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.

Moving on to step 11:
91 goes into 880 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 5733.70329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 12:
If we divide 610 by 91, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 5733.703296
If we take 546 away from 610, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 5733.7032967
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
91 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 5733.7032967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 5733.7032967, and the remainder is 3e-08.
