We look at the division of 42338437 by 91 
We want to divide 42338437 by 91.

Let's proceed to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
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

Moving on to step 2:
91 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 91

Going ahead to step 3:
If we divide 423 by 91, we get 4 and a remainder of 59.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 59 after subtracting 364 from 423.
Include the next digit (3) from the dividend after 59, then repeat: 593 / 91

Going ahead to step 4:
593 divided by 91 is 6 with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we subtract 546 from 593, we get 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 91

Let's proceed to step 5:
When dividing 478 by 91, we get 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 465.0
Subtracting 455 from 478 leaves us with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 91

Step 6:
234 divided by 91 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 4652.0
Subtracting 182 from 234 leaves us with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 91

Step 7:
523 divided by 91 is 5 with a remainder of 68.
The next digit of our result is 5. 
Result so far: 46525.0
If we subtract 455 from 523, we get 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 91

Moving on to step 8:
If we divide 687 by 91, we get 7 and a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 465257.0
If we subtract 637 from 687, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
91 goes into 500 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 465257.5
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
If we divide 450 by 91, we get 4 and a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 465257.54
Deduct 364 from 450 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 11:
860 divided by 91 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 465257.549
Subtracting 819 from 860 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
When dividing 410 by 91, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 465257.5494
If we take 364 away from 410, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 13:
If we divide 460 by 91, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 465257.54945
The remainder is 5 after subtracting 455 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 14:
50 divided by 91 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 465257.54945
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
91 can be fit into 500 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 465257.5494505
Deduct 455 from 500 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 16:
If we divide 450 by 91, we get 4 and a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 465257.54945054
The remainder is 86 after subtracting 364 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 465257.54945054 with a balance of 8.6e-08.
