We're dividing 418900 by 91 
We want to figure out the number of times 418900 can be divided by 91.

Let's proceed to step 1:
4 divided by 91 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 91

Moving on to step 2:
When dividing 41 by 91, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 91

Let's proceed to step 3:
91 goes into 418 4 times with a remainder of 54.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 364 from 418 leaves us with 54.
Include the next digit (9) from the dividend after 54, then repeat: 549 / 91

Going ahead to step 4:
When dividing 549 by 91, we get 6 with a remainder of 3.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 546 from 549, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 91

Step 5:
30 divided by 91 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 460.0
If we take 0 away from 30, we end up with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 91

Advancing to step 6:
91 can be fit into 300 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 4603.0
If we take 273 away from 300, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 91, we get 2 and a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 4603.2
Subtract 182 from 270 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 8:
The number 91 fits into 880 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 4603.29
The remainder is 61 after subtracting 819 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
If we divide 610 by 91, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 4603.296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
640 divided by 91 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 4603.2967
The remainder is 3 after subtracting 637 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
30 divided by 91 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4603.2967
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
When dividing 300 by 91, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 4603.296703
Subtracting 273 from 300 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
91 goes into 270 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 4603.2967032
The remainder is 88 after subtracting 182 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 14:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 4603.29670329
If we subtract 819 from 880, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final outcome is 4603.29670329, with a leftover of 6.1e-08.
