426406 divided by 91 
We want to figure out the number of times 426406 can be divided by 91.

Advancing to step 1:
If we divide 4 by 91, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 91

On to step 2:
When dividing 42 by 91, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 91

Step 3:
When dividing 426 by 91, we get 4 with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 364 from 426 and we're left with 62.
Fetch the next digit (4) from the dividend, attach it to 62 and continue: 624 / 91

On to step 4:
91 can be fit into 624 6 times, resulting in a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtracting 546 from 624 leaves us with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 91

Advancing to step 5:
91 goes into 780 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 468.0
If we take 728 away from 780, we end up with 52.
Fetch the next digit (6) from the dividend, attach it to 52 and continue: 526 / 91

Step 6:
526 divided by 91 is 5 with a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 4685.0
If we take 455 away from 526, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
If we divide 710 by 91, we get 7 and a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 4685.7
Subtract 637 from 710 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 8:
91 goes into 730 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 4685.78
Subtract 728 from 730 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 91, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4685.78
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
91 goes into 200 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 4685.7802
If we subtract 182 from 200, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
91 can be fit into 180 1 times, resulting in a remainder of 89.
Record the quotient 1 as the next digit in the result. 
Result so far: 4685.78021
If we take 91 away from 180, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 12:
91 goes into 890 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 4685.780219
If we take 819 away from 890, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 13:
710 divided by 91 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 4685.7802197
Subtract 637 from 710 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 14:
When dividing 730 by 91, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 4685.78021978
Deduct 728 from 730 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 4685.78021978, with a leftover of 2e-09.
