426509 divided by 91 
We want to divide 426509 by 91.

Advancing to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 91

Let's proceed to step 2:
The number 91 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 91

On to step 3:
426 divided by 91 is 4 with a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 364 away from 426, we end up with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 91

Step 4:
91 goes into 625 6 times with a remainder of 79.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 546 from 625 to get 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 91

Step 5:
When dividing 790 by 91, we get 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 468.0
Subtracting 728 from 790 leaves us with 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 91

Advancing to step 6:
When dividing 629 by 91, we get 6 with a remainder of 83.
The number 6 becomes the next digit in our result. 
Result so far: 4686.0
Deduct 546 from 629 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 7:
If we divide 830 by 91, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 4686.9
Subtract 819 from 830 to 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.

Advancing to step 8:
When dividing 110 by 91, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4686.91
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.

Moving on to step 9:
91 can be fit into 190 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 4686.912
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.

Moving on to step 10:
If we divide 80 by 91, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4686.912
If we subtract 0 from 80, we 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 11:
When dividing 800 by 91, we get 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 4686.91208
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
When dividing 720 by 91, we get 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 4686.912087
Deduct 637 from 720 and we're left with 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 13:
830 divided by 91 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4686.9120879
Deduct 819 from 830 and we're left 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 14:
110 divided by 91 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4686.91208791
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.

After the division, we end up with 4686.91208791 and a remainder of 1.9e-08.
