We look at the division of 12256446 by 658 
We're looking to find how many times 658 goes into 12256446.

Going ahead to step 1:
If we divide 1 by 658, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 658

Advancing to step 2:
658 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 658

Let's proceed to step 3:
658 goes into 122 0 times with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 658

On to step 4:
658 can be fit into 1225 1 times, resulting in a remainder of 567.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 567 after subtracting 658 from 1225.
Include the next digit (6) from the dividend after 567, then repeat: 5676 / 658

On to step 5:
658 can be fit into 5676 8 times, resulting in a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 5264 from 5676 and we're left with 412.
Append the next digit (4) from the dividend to 412 and continue with: 4124 / 658

Going ahead to step 6:
If we divide 4124 by 658, we get 6 and a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 186.0
If we take 3948 away from 4124, we end up with 176.
Bring next digit (4) of the dividend behind the 176 and repeat the process: 1764 / 658

Going ahead to step 7:
658 can be fit into 1764 2 times, resulting in a remainder of 448.
Put 2 as the next digit of the answer. 
Result so far: 1862.0
Subtracting 1316 from 1764 leaves us with 448.
Append the next digit (6) from the dividend to 448 and continue with: 4486 / 658

On to step 8:
658 goes into 4486 6 times with a remainder of 538.
Write down 6 as next digit of the result. 
Result so far: 18626.0
Subtracting 3948 from 4486 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Step 9:
If we divide 5380 by 658, we get 8 and a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 18626.8
If we take 5264 away from 5380, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
When dividing 1160 by 658, we get 1 with a remainder of 502.
Write down 1 as next digit of the result. 
Result so far: 18626.81
Deduct 658 from 1160 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 11:
The number 658 fits into 5020 7 times, leaving a remainder of 414.
The next digit of our result is 7. 
Result so far: 18626.817
If we take 4606 away from 5020, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Step 12:
4140 divided by 658 is 6 with a remainder of 192.
The next digit of our result is 6. 
Result so far: 18626.8176
Subtract 3948 from 4140 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
When dividing 1920 by 658, we get 2 with a remainder of 604.
The next digit of our result is 2. 
Result so far: 18626.81762
The remainder is 604 after subtracting 1316 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Step 14:
The number 658 fits into 6040 9 times, leaving a remainder of 118.
The next digit of our result is 9. 
Result so far: 18626.817629
If we take 5922 away from 6040, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 15:
658 goes into 1180 1 times with a remainder of 522.
Put 1 as the next digit of the answer. 
Result so far: 18626.8176291
Subtracting 658 from 1180 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 16:
If we divide 5220 by 658, we get 7 and a remainder of 614.
The number 7 becomes the next digit in our result. 
Result so far: 18626.81762917
If we take 4606 away from 5220, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The final result is 18626.81762917 with a remainder of 6.14e-07.
