Let's divide 91284409 by 252
We want to figure out the number of times 91284409 can be divided by 252.

On to step 1:
252 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 252

Moving on to step 2:
252 goes into 91 0 times with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 252

Going ahead to step 3:
The number 252 fits into 912 3 times, leaving a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 156 after subtracting 756 from 912.
Include the next digit (8) from the dividend after 156, then repeat: 1568 / 252

Advancing to step 4:
1568 divided by 252 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 1512 away from 1568, we end up with 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 252

Advancing to step 5:
252 can be fit into 564 2 times, resulting in a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 362.0
Deduct 504 from 564 and we're left with 60.
Fetch the next digit (4) from the dividend, attach it to 60 and continue: 604 / 252

Step 6:
252 can be fit into 604 2 times, resulting in a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 3622.0
Deduct 504 from 604 and we're left with 100.
Bring next digit (0) of the dividend behind the 100 and repeat the process: 1000 / 252

On to step 7:
When dividing 1000 by 252, we get 3 with a remainder of 244.
Record the quotient 3 as the next digit in the result. 
Result so far: 36223.0
Deduct 756 from 1000 and we're left with 244.
Take the next digit (9) from the dividend and append it to 244, then repeat: 2449 / 252

Advancing to step 8:
252 goes into 2449 9 times with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 362239.0
Subtracting 2268 from 2449 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 9:
When dividing 1810 by 252, we get 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 362239.7
Subtracting 1764 from 1810 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
When dividing 460 by 252, we get 1 with a remainder of 208.
The next digit of our result is 1. 
Result so far: 362239.71
Subtracting 252 from 460 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
When dividing 2080 by 252, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 362239.718
Subtract 2016 from 2080 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
252 goes into 640 2 times with a remainder of 136.
The next digit of our result is 2. 
Result so far: 362239.7182
If we take 504 away from 640, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 13:
1360 divided by 252 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 362239.71825
If we take 1260 away from 1360, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 14:
When dividing 1000 by 252, we get 3 with a remainder of 244.
Use 3 as the next digit of our solution. 
Result so far: 362239.718253
If we subtract 756 from 1000, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Step 15:
If we divide 2440 by 252, we get 9 and a remainder of 172.
The number 9 becomes the next digit in our result. 
Result so far: 362239.7182539
If we take 2268 away from 2440, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 16:
If we divide 1720 by 252, we get 6 and a remainder of 208.
Write down 6 as next digit of the result. 
Result so far: 362239.71825396
The remainder is 208 after subtracting 1512 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 362239.71825396, with a leftover of 2.08e-07.
