We're dividing 22129405 by 864 
We want to figure out the number of times 22129405 can be divided by 864.

Advancing to step 1:
The number 864 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 864

Let's proceed to step 2:
The number 864 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 864

Step 3:
If we divide 221 by 864, we get 0 and a remainder of 221.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 221, we get 221.
Bring next digit (2) of the dividend behind the 221 and repeat the process: 2212 / 864

Going ahead to step 4:
864 can be fit into 2212 2 times, resulting in a remainder of 484.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 484 after subtracting 1728 from 2212.
Grab the next digit (9) from the dividend, add it to 484, then carry on: 4849 / 864

Step 5:
If we divide 4849 by 864, we get 5 and a remainder of 529.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 4320 from 4849 to get 529.
Include the next digit (4) from the dividend after 529, then repeat: 5294 / 864

Step 6:
5294 divided by 864 is 6 with a remainder of 110.
The next digit of our result is 6. 
Result so far: 256.0
Subtract 5184 from 5294 to get 110.
Fetch the next digit (0) from the dividend, attach it to 110 and continue: 1100 / 864

Step 7:
If we divide 1100 by 864, we get 1 and a remainder of 236.
Write down 1 as next digit of the result. 
Result so far: 2561.0
The remainder is 236 after subtracting 864 from 1100.
Append the next digit (5) from the dividend to 236 and continue with: 2365 / 864

Going ahead to step 8:
864 can be fit into 2365 2 times, resulting in a remainder of 637.
Record the quotient 2 as the next digit in the result. 
Result so far: 25612.0
Deduct 1728 from 2365 and we're left with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Let's proceed to step 9:
6370 divided by 864 is 7 with a remainder of 322.
Write down 7 as next digit of the result. 
Result so far: 25612.7
Subtracting 6048 from 6370 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 10:
The number 864 fits into 3220 3 times, leaving a remainder of 628.
Write down 3 as next digit of the result. 
Result so far: 25612.73
Subtract 2592 from 3220 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 11:
If we divide 6280 by 864, we get 7 and a remainder of 232.
Record the quotient 7 as the next digit in the result. 
Result so far: 25612.737
If we take 6048 away from 6280, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 12:
When dividing 2320 by 864, we get 2 with a remainder of 592.
Put 2 as the next digit of the answer. 
Result so far: 25612.7372
If we subtract 1728 from 2320, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Advancing to step 13:
864 can be fit into 5920 6 times, resulting in a remainder of 736.
The next digit of our result is 6. 
Result so far: 25612.73726
Subtract 5184 from 5920 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 14:
The number 864 fits into 7360 8 times, leaving a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 25612.737268
If we take 6912 away from 7360, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 15:
864 goes into 4480 5 times with a remainder of 160.
Record the quotient 5 as the next digit in the result. 
Result so far: 25612.7372685
The remainder is 160 after subtracting 4320 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
1600 divided by 864 is 1 with a remainder of 736.
Put 1 as the next digit of the answer. 
Result so far: 25612.73726851
Subtracting 864 from 1600 leaves us with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

The final outcome is 25612.73726851, with a leftover of 7.36e-07.
