Advancing to step 4:
5574 divided by 646 is 8 with a remainder of 406.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 5168 from 5574 and we're left with 406.
Append the next digit (3) from the dividend to 406 and continue with: 4063 / 646

Step 5:
646 goes into 4063 6 times with a remainder of 187.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 3876 from 4063 leaves us with 187.
Append the next digit (6) from the dividend to 187 and continue with: 1876 / 646

Step 6:
646 can be fit into 1876 2 times, resulting in a remainder of 584.
Use 2 as the next digit of our solution. 
Result so far: 862.0
Subtracting 1292 from 1876 leaves us with 584.
Fetch the next digit (7) from the dividend, attach it to 584 and continue: 5847 / 646

Step 7:
When dividing 5847 by 646, we get 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 8629.0
Subtract 5814 from 5847 to get 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 646

Moving on to step 8:
The number 646 fits into 332 0 times, leaving a remainder of 332.
The next digit of our result is 0. 
Result so far: 86290.0
If we take 0 away from 332, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 9:
646 can be fit into 3320 5 times, resulting in a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 86290.5
If we subtract 3230 from 3320, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
The number 646 fits into 900 1 times, leaving a remainder of 254.
Record the quotient 1 as the next digit in the result. 
Result so far: 86290.51
Subtracting 646 from 900 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 11:
2540 divided by 646 is 3 with a remainder of 602.
Write down 3 as next digit of the result. 
Result so far: 86290.513
Deduct 1938 from 2540 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Step 12:
646 can be fit into 6020 9 times, resulting in a remainder of 206.
Record the quotient 9 as the next digit in the result. 
Result so far: 86290.5139
If we subtract 5814 from 6020, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 13:
646 can be fit into 2060 3 times, resulting in a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 86290.51393
The remainder is 122 after subtracting 1938 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 14:
646 goes into 1220 1 times with a remainder of 574.
Put 1 as the next digit of the answer. 
Result so far: 86290.513931
If we take 646 away from 1220, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Moving on to step 15:
646 can be fit into 5740 8 times, resulting in a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 86290.5139318
Subtracting 5168 from 5740 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 16:
646 goes into 5720 8 times with a remainder of 552.
Use 8 as the next digit of our solution. 
Result so far: 86290.51393188
Deduct 5168 from 5720 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

In conclusion, the division gives 86290.51393188 with a balance of 5.52e-07.
