When dividing 1976 by 522, we get 3 with a remainder of 410.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 410 after subtracting 1566 from 1976.
Append the next digit (1) from the dividend to 410 and continue with: 4101 / 522

Advancing to step 5:
522 goes into 4101 7 times with a remainder of 447.
The next digit of our result is 7. 
Result so far: 137.0
Deduct 3654 from 4101 and we're left with 447.
Fetch the next digit (8) from the dividend, attach it to 447 and continue: 4478 / 522

Going ahead to step 6:
522 can be fit into 4478 8 times, resulting in a remainder of 302.
Record the quotient 8 as the next digit in the result. 
Result so far: 1378.0
Subtracting 4176 from 4478 leaves us with 302.
Fetch the next digit (6) from the dividend, attach it to 302 and continue: 3026 / 522

Advancing to step 7:
If we divide 3026 by 522, we get 5 and a remainder of 416.
Write down 5 as next digit of the result. 
Result so far: 13785.0
Subtracting 2610 from 3026 leaves us with 416.
Bring next digit (1) of the dividend behind the 416 and repeat the process: 4161 / 522

On to step 8:
When dividing 4161 by 522, we get 7 with a remainder of 507.
The number 7 becomes the next digit in our result. 
Result so far: 137857.0
Subtracting 3654 from 4161 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Going ahead to step 9:
522 can be fit into 5070 9 times, resulting in a remainder of 372.
Put 9 as the next digit of the answer. 
Result so far: 137857.9
If we subtract 4698 from 5070, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 10:
The number 522 fits into 3720 7 times, leaving a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 137857.97
Subtracting 3654 from 3720 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 11:
522 can be fit into 660 1 times, resulting in a remainder of 138.
The next digit of our result is 1. 
Result so far: 137857.971
If we take 522 away from 660, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 12:
If we divide 1380 by 522, we get 2 and a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 137857.9712
Deduct 1044 from 1380 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 13:
If we divide 3360 by 522, we get 6 and a remainder of 228.
Write down 6 as next digit of the result. 
Result so far: 137857.97126
If we take 3132 away from 3360, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 14:
522 can be fit into 2280 4 times, resulting in a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 137857.971264
Subtract 2088 from 2280 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 15:
The number 522 fits into 1920 3 times, leaving a remainder of 354.
Write down 3 as next digit of the result. 
Result so far: 137857.9712643
The remainder is 354 after subtracting 1566 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 16:
522 goes into 3540 6 times with a remainder of 408.
The next digit of our result is 6. 
Result so far: 137857.97126436
The remainder is 408 after subtracting 3132 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

In conclusion, the division gives 137857.97126436 with a balance of 4.08e-07.
