On to step 7:
3071 divided by 657 is 4 with a remainder of 443.
The number 4 becomes the next digit in our result. 
Result so far: 2074.0
The remainder is 443 after subtracting 2628 from 3071.
Grab the next digit (2) from the dividend, add it to 443, then carry on: 4432 / 657

Advancing to step 8:
When dividing 4432 by 657, we get 6 with a remainder of 490.
Use 6 as the next digit of our solution. 
Result so far: 20746.0
Deduct 3942 from 4432 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Advancing to step 9:
If we divide 4900 by 657, we get 7 and a remainder of 301.
The next digit of our result is 7. 
Result so far: 20746.7
The remainder is 301 after subtracting 4599 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 10:
657 can be fit into 3010 4 times, resulting in a remainder of 382.
The number 4 becomes the next digit in our result. 
Result so far: 20746.74
Deduct 2628 from 3010 and we're left with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 11:
657 can be fit into 3820 5 times, resulting in a remainder of 535.
Put 5 as the next digit of the answer. 
Result so far: 20746.745
Subtracting 3285 from 3820 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 12:
The number 657 fits into 5350 8 times, leaving a remainder of 94.
Use 8 as the next digit of our solution. 
Result so far: 20746.7458
The remainder is 94 after subtracting 5256 from 5350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 13:
When dividing 940 by 657, we get 1 with a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 20746.74581
Deduct 657 from 940 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 14:
657 goes into 2830 4 times with a remainder of 202.
Put 4 as the next digit of the answer. 
Result so far: 20746.745814
Deduct 2628 from 2830 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 15:
When dividing 2020 by 657, we get 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 20746.7458143

Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 16:
If we divide 490 by 657, we get 0 and a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 20746.7458143
If we subtract 0 from 490, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.
