91644493 ÷ 465 
We want to figure out the number of times 91644493 can be divided by 465.

On to step 1:
9 divided by 465 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 465

Advancing to step 2:
465 can be fit into 91 0 times, resulting in a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 465

Moving on to step 3:
The number 465 fits into 916 1 times, leaving a remainder of 451.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 451 after subtracting 465 from 916.
Take the next digit (4) from the dividend and append it to 451, then repeat: 4514 / 465

Going ahead to step 4:
465 goes into 4514 9 times with a remainder of 329.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 4185 from 4514, we get 329.
Append the next digit (4) from the dividend to 329 and continue with: 3294 / 465

Step 5:
465 can be fit into 3294 7 times, resulting in a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 197.0
The remainder is 39 after subtracting 3255 from 3294.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 465

Step 6:
When dividing 394 by 465, we get 0 with a remainder of 394.
The number 0 becomes the next digit in our result. 
Result so far: 1970.0
Subtracting 0 from 394 leaves us with 394.
Include the next digit (9) from the dividend after 394, then repeat: 3949 / 465

Step 7:
The number 465 fits into 3949 8 times, leaving a remainder of 229.
Use 8 as the next digit of our solution. 
Result so far: 19708.0
Deduct 3720 from 3949 and we're left with 229.
Fetch the next digit (3) from the dividend, attach it to 229 and continue: 2293 / 465

Let's proceed to step 8:
When dividing 2293 by 465, we get 4 with a remainder of 433.
The next digit of our result is 4. 
Result so far: 197084.0
Subtracting 1860 from 2293 leaves us with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 9:
The number 465 fits into 4330 9 times, leaving a remainder of 145.
Use 9 as the next digit of our solution. 
Result so far: 197084.9
If we subtract 4185 from 4330, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 10:
465 can be fit into 1450 3 times, resulting in a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 197084.93
Subtracting 1395 from 1450 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
465 can be fit into 550 1 times, resulting in a remainder of 85.
The next digit of our result is 1. 
Result so far: 197084.931
If we subtract 465 from 550, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 12:
When dividing 850 by 465, we get 1 with a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 197084.9311
If we take 465 away from 850, we end up with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

After the division, we end up with 197084.9311 and a remainder of 0.00385.
