We're dividing 424386 by 91 
We want to figure out the number of times 424386 can be divided by 91.

On to step 1:
91 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 91

Advancing to step 2:
When dividing 42 by 91, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 91

Moving on to step 3:
When dividing 424 by 91, we get 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 364 from 424 to get 60.
Include the next digit (3) from the dividend after 60, then repeat: 603 / 91

Step 4:
When dividing 603 by 91, we get 6 with a remainder of 57.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 546 from 603, we get 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 91

Advancing to step 5:
If we divide 578 by 91, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 466.0
Deduct 546 from 578 and we're left with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 91

Step 6:
326 divided by 91 is 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 4663.0
The remainder is 53 after subtracting 273 from 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
When dividing 530 by 91, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 4663.5
Subtract 455 from 530 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
The number 91 fits into 750 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 4663.58
Subtract 728 from 750 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 91 fits into 220 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 4663.582
The remainder is 38 after subtracting 182 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
When dividing 380 by 91, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4663.5824
Deduct 364 from 380 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
91 can be fit into 160 1 times, resulting in a remainder of 69.
The next digit of our result is 1. 
Result so far: 4663.58241
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
91 goes into 690 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 4663.582417
If we take 637 away from 690, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
When dividing 530 by 91, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 4663.5824175
Deduct 455 from 530 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 91 fits into 750 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 4663.58241758
If we subtract 728 from 750, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 4663.58241758 with a remainder of 2.2e-08.
