We're dividing 31698129 by 521 
Let's see how many times 521 fits into 31698129.

Step 1:
521 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 521

On to step 2:
521 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 521

Step 3:
When dividing 316 by 521, we get 0 with a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 316, we end up with 316.
Grab the next digit (9) from the dividend, add it to 316, then carry on: 3169 / 521

Moving on to step 4:
If we divide 3169 by 521, we get 6 and a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 3126 away from 3169, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 521

Let's proceed to step 5:
If we divide 438 by 521, we get 0 and a remainder of 438.
The next digit of our result is 0. 
Result so far: 60.0
The remainder is 438 after subtracting 0 from 438.
Bring next digit (1) of the dividend behind the 438 and repeat the process: 4381 / 521

Advancing to step 6:
521 can be fit into 4381 8 times, resulting in a remainder of 213.
Use 8 as the next digit of our solution. 
Result so far: 608.0
If we subtract 4168 from 4381, we get 213.
Append the next digit (2) from the dividend to 213 and continue with: 2132 / 521

Advancing to step 7:
521 goes into 2132 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 6084.0
Deduct 2084 from 2132 and we're left with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 521

Step 8:
The number 521 fits into 489 0 times, leaving a remainder of 489.
Put 0 as the next digit of the answer. 
Result so far: 60840.0
Subtracting 0 from 489 leaves us with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Going ahead to step 9:
521 can be fit into 4890 9 times, resulting in a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 60840.9
Subtracting 4689 from 4890 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 10:
The number 521 fits into 2010 3 times, leaving a remainder of 447.
Use 3 as the next digit of our solution. 
Result so far: 60840.93
The remainder is 447 after subtracting 1563 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 11:
521 can be fit into 4470 8 times, resulting in a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 60840.938
Deduct 4168 from 4470 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 12:
521 goes into 3020 5 times with a remainder of 415.
Use 5 as the next digit of our solution. 
Result so far: 60840.9385
Subtract 2605 from 3020 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 13:
521 goes into 4150 7 times with a remainder of 503.
Use 7 as the next digit of our solution. 
Result so far: 60840.93857
If we subtract 3647 from 4150, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Advancing to step 14:
5030 divided by 521 is 9 with a remainder of 341.
The number 9 becomes the next digit in our result. 
Result so far: 60840.938579
If we take 4689 away from 5030, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

On to step 15:
When dividing 3410 by 521, we get 6 with a remainder of 284.
Record the quotient 6 as the next digit in the result. 
Result so far: 60840.9385796
Subtract 3126 from 3410 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 16:
The number 521 fits into 2840 5 times, leaving a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 60840.93857965
Subtract 2605 from 2840 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

After the division, we end up with 60840.93857965 and a remainder of 2.35e-07.
