21117134 divided by 465 
We want to figure out the number of times 21117134 can be divided by 465.

Moving on to step 1:
465 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 465

Step 2:
465 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 465

Going ahead to step 3:
465 goes into 211 0 times with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Include the next digit (1) from the dividend after 211, then repeat: 2111 / 465

Step 4:
465 can be fit into 2111 4 times, resulting in a remainder of 251.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1860 from 2111 to get 251.
Take the next digit (7) from the dividend and append it to 251, then repeat: 2517 / 465

On to step 5:
The number 465 fits into 2517 5 times, leaving a remainder of 192.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 2325 from 2517 leaves us with 192.
Bring next digit (1) of the dividend behind the 192 and repeat the process: 1921 / 465

Let's proceed to step 6:
When dividing 1921 by 465, we get 4 with a remainder of 61.
The next digit of our result is 4. 
Result so far: 454.0
If we take 1860 away from 1921, we end up with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 465

Advancing to step 7:
The number 465 fits into 613 1 times, leaving a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 4541.0
If we subtract 465 from 613, we get 148.
Fetch the next digit (4) from the dividend, attach it to 148 and continue: 1484 / 465

Going ahead to step 8:
465 can be fit into 1484 3 times, resulting in a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 45413.0
Deduct 1395 from 1484 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
890 divided by 465 is 1 with a remainder of 425.
Use 1 as the next digit of our solution. 
Result so far: 45413.1
The remainder is 425 after subtracting 465 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Let's proceed to step 10:
465 can be fit into 4250 9 times, resulting in a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 45413.19
Deduct 4185 from 4250 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
650 divided by 465 is 1 with a remainder of 185.
Write down 1 as next digit of the result. 
Result so far: 45413.191
Subtracting 465 from 650 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 12:
465 goes into 1850 3 times with a remainder of 455.
Use 3 as the next digit of our solution. 
Result so far: 45413.1913
Deduct 1395 from 1850 and we're left with 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

On to step 13:
465 goes into 4550 9 times with a remainder of 365.
The number 9 becomes the next digit in our result. 
Result so far: 45413.19139
The remainder is 365 after subtracting 4185 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 14:
465 goes into 3650 7 times with a remainder of 395.
The number 7 becomes the next digit in our result. 
Result so far: 45413.191397
The remainder is 395 after subtracting 3255 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 15:
When dividing 3950 by 465, we get 8 with a remainder of 230.
The next digit of our result is 8. 
Result so far: 45413.1913978
Deduct 3720 from 3950 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 16:
The number 465 fits into 2300 4 times, leaving a remainder of 440.
The number 4 becomes the next digit in our result. 
Result so far: 45413.19139784
Subtract 1860 from 2300 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 45413.19139784, with a leftover of 4.4e-07.
