520448 ÷ 91 
We want to figure out the number of times 520448 can be divided by 91.

Moving on to step 1:
When dividing 5 by 91, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 91

Advancing to step 2:
91 goes into 52 0 times with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 91

Going ahead to step 3:
When dividing 520 by 91, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 455 from 520 to get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 91

Going ahead to step 4:
If we divide 654 by 91, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 637 from 654 and we're left with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 91

Moving on to step 5:
The number 91 fits into 174 1 times, leaving a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 571.0
The remainder is 83 after subtracting 91 from 174.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 91

Step 6:
When dividing 838 by 91, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 5719.0
If we take 819 away from 838, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 91 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5719.2
If we subtract 182 from 190, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 91, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 5719.2
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 9:
If we divide 800 by 91, we get 8 and a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 5719.208
Subtract 728 from 800 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
The number 91 fits into 720 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 5719.2087
The remainder is 83 after subtracting 637 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 11:
When dividing 830 by 91, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 5719.20879
The remainder is 11 after subtracting 819 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
When dividing 110 by 91, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 5719.208791
Deduct 91 from 110 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
91 can be fit into 190 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 5719.2087912
The remainder is 8 after subtracting 182 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
When dividing 80 by 91, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 5719.2087912
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 5719.2087912 with a balance of 8e-08.
