Step 7:
4417 divided by 642 is 6 with a remainder of 565.
Record the quotient 6 as the next digit in the result. 
Result so far: 5476.0
Subtracting 3852 from 4417 leaves us with 565.
Grab the next digit (2) from the dividend, add it to 565, then carry on: 5652 / 642

Step 8:
642 can be fit into 5652 8 times, resulting in a remainder of 516.
Use 8 as the next digit of our solution. 
Result so far: 54768.0
If we take 5136 away from 5652, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 9:
When dividing 5160 by 642, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 54768.8
Subtracting 5136 from 5160 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
642 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 54768.8
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
642 can be fit into 2400 3 times, resulting in a remainder of 474.
Use 3 as the next digit of our solution. 
Result so far: 54768.803
Subtracting 1926 from 2400 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 12:
642 goes into 4740 7 times with a remainder of 246.
The next digit of our result is 7. 
Result so far: 54768.8037
Deduct 4494 from 4740 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 13:
2460 divided by 642 is 3 with a remainder of 534.
Record the quotient 3 as the next digit in the result. 
Result so far: 54768.80373
If we take 1926 away from 2460, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 14:
If we divide 5340 by 642, we get 8 and a remainder of 204.
The next digit of our result is 8. 
Result so far: 54768.803738
If we subtract 5136 from 5340, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 15:
642 goes into 2040 3 times with a remainder of 114.
Record the quotient 3 as the next digit in the result. 
Result so far: 54768.8037383
Subtracting 1926 from 2040 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 16:
642 can be fit into 1140 1 times, resulting in a remainder of 498.
Use 1 as the next digit of our solution. 
Result so far: 54768.80373831
Subtract 642 from 1140 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

The quotient of the division is 54768.80373831, and the remainder is 4.98e-07.
