45189449 divided by 91 
We want to figure out the number of times 45189449 can be divided by 91.

On to step 1:
91 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 91

On to step 2:
91 goes into 45 0 times with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 91

Moving on to step 3:
451 divided by 91 is 4 with a remainder of 87.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 364 from 451 leaves us with 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 91

On to step 4:
878 divided by 91 is 9 with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we take 819 away from 878, we end up with 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 91

On to step 5:
91 goes into 599 6 times with a remainder of 53.
The next digit of our result is 6. 
Result so far: 496.0
The remainder is 53 after subtracting 546 from 599.
Append the next digit (4) from the dividend to 53 and continue with: 534 / 91

Moving on to step 6:
534 divided by 91 is 5 with a remainder of 79.
The next digit of our result is 5. 
Result so far: 4965.0
Subtract 455 from 534 to get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 91

Advancing to step 7:
794 divided by 91 is 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 49658.0
If we subtract 728 from 794, we get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 91

On to step 8:
91 can be fit into 669 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 496587.0
Subtract 637 from 669 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
91 can be fit into 320 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 496587.3
The remainder is 47 after subtracting 273 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
When dividing 470 by 91, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 496587.35
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
When dividing 150 by 91, we get 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 496587.351
The remainder is 59 after subtracting 91 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 12:
91 goes into 590 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 496587.3516
Subtract 546 from 590 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
91 can be fit into 440 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 496587.35164
Deduct 364 from 440 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
The number 91 fits into 760 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 496587.351648
Subtracting 728 from 760 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 15:
91 goes into 320 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 496587.3516483
If we subtract 273 from 320, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 16:
The number 91 fits into 470 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 496587.35164835
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 496587.35164835 with a balance of 1.5e-08.
