44645699 ÷ 91 
Our goal is to divide 44645699 by 91.

Going ahead to step 1:
When dividing 4 by 91, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 91

Going ahead to step 2:
91 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 91

On to step 3:
When dividing 446 by 91, we get 4 with a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 364 from 446 and we're left with 82.
Bring next digit (4) of the dividend behind the 82 and repeat the process: 824 / 91

Moving on to step 4:
If we divide 824 by 91, we get 9 and a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Deduct 819 from 824 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 91

Moving on to step 5:
If we divide 55 by 91, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 490.0
Subtracting 0 from 55 leaves us with 55.
Append the next digit (6) from the dividend to 55 and continue with: 556 / 91

On to step 6:
If we divide 556 by 91, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4906.0
If we subtract 546 from 556, we get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 91

Advancing to step 7:
If we divide 109 by 91, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 49061.0
If we take 91 away from 109, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 91

Advancing to step 8:
If we divide 189 by 91, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 490612.0
If we take 182 away from 189, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
91 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 490612.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
91 goes into 700 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 490612.07
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 11:
630 divided by 91 is 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 490612.076
Subtract 546 from 630 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
When dividing 840 by 91, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 490612.0769
If we take 819 away from 840, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
91 goes into 210 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 490612.07692
Deduct 182 from 210 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
The number 91 fits into 280 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 490612.076923
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 15:
If we divide 70 by 91, we get 0 and a remainder of 70.
The next digit of our result is 0. 
Result so far: 490612.076923
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
91 can be fit into 700 7 times, resulting in a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 490612.07692307
Subtracting 637 from 700 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 490612.07692307 with a remainder of 6.3e-08.
