We divide 54578854 by 658
We're looking to find how many times 658 goes into 54578854.

Step 1:
If we divide 5 by 658, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 658

On to step 2:
54 divided by 658 is 0 with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 658

Step 3:
545 divided by 658 is 0 with a remainder of 545.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 545 after subtracting 0 from 545.
Append the next digit (7) from the dividend to 545 and continue with: 5457 / 658

Advancing to step 4:
658 can be fit into 5457 8 times, resulting in a remainder of 193.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 5264 from 5457 leaves us with 193.
Take the next digit (8) from the dividend and append it to 193, then repeat: 1938 / 658

Moving on to step 5:
658 can be fit into 1938 2 times, resulting in a remainder of 622.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1316 from 1938 and we're left with 622.
Include the next digit (8) from the dividend after 622, then repeat: 6228 / 658

Moving on to step 6:
658 can be fit into 6228 9 times, resulting in a remainder of 306.
The next digit of our result is 9. 
Result so far: 829.0
If we take 5922 away from 6228, we end up with 306.
Include the next digit (5) from the dividend after 306, then repeat: 3065 / 658

Going ahead to step 7:
3065 divided by 658 is 4 with a remainder of 433.
Put 4 as the next digit of the answer. 
Result so far: 8294.0
If we take 2632 away from 3065, we end up with 433.
Take the next digit (4) from the dividend and append it to 433, then repeat: 4334 / 658

Going ahead to step 8:
4334 divided by 658 is 6 with a remainder of 386.
Write down 6 as next digit of the result. 
Result so far: 82946.0
If we take 3948 away from 4334, we end up with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 9:
If we divide 3860 by 658, we get 5 and a remainder of 570.
Put 5 as the next digit of the answer. 
Result so far: 82946.5
If we take 3290 away from 3860, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 10:
5700 divided by 658 is 8 with a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 82946.58
Subtracting 5264 from 5700 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 11:
4360 divided by 658 is 6 with a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 82946.586
Subtracting 3948 from 4360 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 12:
658 goes into 4120 6 times with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 82946.5866
Deduct 3948 from 4120 and we're left 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.

After the division, we end up with 82946.5866 and a remainder of 0.00172.
