Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 367 after subtracting 2504 from 2871.
Grab the next digit (1) from the dividend, add it to 367, then carry on: 3671 / 626

Going ahead to step 5:
3671 divided by 626 is 5 with a remainder of 541.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
The remainder is 541 after subtracting 3130 from 3671.
Take the next digit (8) from the dividend and append it to 541, then repeat: 5418 / 626

On to step 6:
626 can be fit into 5418 8 times, resulting in a remainder of 410.
The next digit of our result is 8. 
Result so far: 1458.0
If we take 5008 away from 5418, we end up with 410.
Append the next digit (9) from the dividend to 410 and continue with: 4109 / 626

Let's proceed to step 7:
When dividing 4109 by 626, we get 6 with a remainder of 353.
Write down 6 as next digit of the result. 
Result so far: 14586.0
If we take 3756 away from 4109, we end up with 353.
Include the next digit (7) from the dividend after 353, then repeat: 3537 / 626

On to step 8:
3537 divided by 626 is 5 with a remainder of 407.
Use 5 as the next digit of our solution. 
Result so far: 145865.0
Subtracting 3130 from 3537 leaves us with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Advancing to step 9:
When dividing 4070 by 626, we get 6 with a remainder of 314.
Put 6 as the next digit of the answer. 
Result so far: 145865.6
If we subtract 3756 from 4070, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Moving on to step 10:
The number 626 fits into 3140 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 145865.65
If we subtract 3130 from 3140, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 626 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 145865.65
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
626 can be fit into 1000 1 times, resulting in a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 145865.6501
The remainder is 374 after subtracting 626 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 13:
If we divide 3740 by 626, we get 5 and a remainder of 610.
Use 5 as the next digit of our solution. 
Result so far: 145865.65015
Deduct 3130 from 3740 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 14:
When dividing 6100 by 626, we get 9 with a remainder of 466.
Put 9 as the next digit of the answer. 
Result so far: 145865.650159
Subtract 5634 from 6100 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 15:
If we divide 4660 by 626, we get 7 and a remainder of 278.
The next digit of our result is 7. 
Result so far: 145865.6501597
The remainder is 278 after subtracting 4382 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Let's proceed to step 16:
If we divide 2780 by 626, we get 4 and a remainder of 276.
Record the quotient 4 as the next digit in the result. 
Result so far: 145865.65015974
Subtracting 2504 from 2780 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

In conclusion, the division gives 145865.65015974 with a balance of 2.76e-07.
