Let's divide 91621390 by 452
We want to figure out the number of times 91621390 can be divided by 452.

Moving on to step 1:
If we divide 9 by 452, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 452

Step 2:
452 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
The remainder is 91 after subtracting 0 from 91.
Bring next digit (6) of the dividend behind the 91 and repeat the process: 916 / 452

Advancing to step 3:
When dividing 916 by 452, we get 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 904 from 916 to get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 452

Let's proceed to step 4:
452 can be fit into 122 0 times, resulting in a remainder of 122.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 122 leaves us with 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 452

Advancing to step 5:
When dividing 1221 by 452, we get 2 with a remainder of 317.
Use 2 as the next digit of our solution. 
Result so far: 202.0
If we subtract 904 from 1221, we get 317.
Append the next digit (3) from the dividend to 317 and continue with: 3173 / 452

Let's proceed to step 6:
The number 452 fits into 3173 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 2027.0
If we subtract 3164 from 3173, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 452

Moving on to step 7:
452 goes into 99 0 times with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 20270.0
The remainder is 99 after subtracting 0 from 99.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 452

Advancing to step 8:
If we divide 990 by 452, we get 2 and a remainder of 86.
The next digit of our result is 2. 
Result so far: 202702.0
If we take 904 away from 990, we end up 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.

On to step 9:
The number 452 fits into 860 1 times, leaving a remainder of 408.
Write down 1 as next digit of the result. 
Result so far: 202702.1
Subtract 452 from 860 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 10:
If we divide 4080 by 452, we get 9 and a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 202702.19
If we take 4068 away from 4080, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
When dividing 120 by 452, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 202702.19
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
452 goes into 1200 2 times with a remainder of 296.
Use 2 as the next digit of our solution. 
Result so far: 202702.1902
If we take 904 away from 1200, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 13:
452 can be fit into 2960 6 times, resulting in a remainder of 248.
The next digit of our result is 6. 
Result so far: 202702.19026
Subtract 2712 from 2960 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 14:
When dividing 2480 by 452, we get 5 with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 202702.190265
The remainder is 220 after subtracting 2260 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 15:
When dividing 2200 by 452, we get 4 with a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 202702.1902654
If we take 1808 away from 2200, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 16:
The number 452 fits into 3920 8 times, leaving a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 202702.19026548
Subtract 3616 from 3920 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Our division results in 202702.19026548 with a remaining 3.04e-07.
