508974 ÷ 91 
We want to figure out the number of times 508974 can be divided by 91.

Advancing to step 1:
91 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 91

Step 2:
91 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 91

Advancing to step 3:
91 goes into 508 5 times with a remainder of 53.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 455 away from 508, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 91

Moving on to step 4:
539 divided by 91 is 5 with a remainder of 84.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 455 from 539 to get 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 91

Going ahead to step 5:
91 can be fit into 847 9 times, resulting in a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 559.0
The remainder is 28 after subtracting 819 from 847.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 91

Going ahead to step 6:
91 can be fit into 284 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 5593.0
Subtracting 273 from 284 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
If we divide 110 by 91, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 5593.1
If we subtract 91 from 110, we get 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 8:
The number 91 fits into 190 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5593.12
If we take 182 away from 190, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
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: 5593.12
Subtracting 0 from 80 leaves us 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.

Let's proceed to step 10:
91 can be fit into 800 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 5593.1208
The remainder is 72 after subtracting 728 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
720 divided by 91 is 7 with a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 5593.12087
Subtract 637 from 720 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 12:
The number 91 fits into 830 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 5593.120879
If we subtract 819 from 830, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
When dividing 110 by 91, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 5593.1208791
If we take 91 away from 110, 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.

Step 14:
If we divide 190 by 91, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5593.12087912
Deduct 182 from 190 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 5593.12087912, with a leftover of 8e-09.
