We're dividing 65959808 by 521 
Let's see how many times 521 fits into 65959808.

Step 1:
The number 521 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 521

On to step 2:
521 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 521

Advancing to step 3:
521 goes into 659 1 times with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 521 from 659 and we're left with 138.
Grab the next digit (5) from the dividend, add it to 138, then carry on: 1385 / 521

Let's proceed to step 4:
521 can be fit into 1385 2 times, resulting in a remainder of 343.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1042 from 1385 and we're left with 343.
Append the next digit (9) from the dividend to 343 and continue with: 3439 / 521

On to step 5:
When dividing 3439 by 521, we get 6 with a remainder of 313.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Deduct 3126 from 3439 and we're left with 313.
Fetch the next digit (8) from the dividend, attach it to 313 and continue: 3138 / 521

Going ahead to step 6:
The number 521 fits into 3138 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1266.0
Subtract 3126 from 3138 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 521

On to step 7:
521 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 12660.0
If we subtract 0 from 120, we get 120.
Include the next digit (8) from the dividend after 120, then repeat: 1208 / 521

Advancing to step 8:
When dividing 1208 by 521, we get 2 with a remainder of 166.
The next digit of our result is 2. 
Result so far: 126602.0
Subtract 1042 from 1208 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
521 can be fit into 1660 3 times, resulting in a remainder of 97.
The next digit of our result is 3. 
Result so far: 126602.3
If we take 1563 away from 1660, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 10:
521 goes into 970 1 times with a remainder of 449.
Record the quotient 1 as the next digit in the result. 
Result so far: 126602.31
If we subtract 521 from 970, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Advancing to step 11:
4490 divided by 521 is 8 with a remainder of 322.
Write down 8 as next digit of the result. 
Result so far: 126602.318
Deduct 4168 from 4490 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 12:
If we divide 3220 by 521, we get 6 and a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 126602.3186
The remainder is 94 after subtracting 3126 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 13:
If we divide 940 by 521, we get 1 and a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 126602.31861
If we take 521 away from 940, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 14:
The number 521 fits into 4190 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 126602.318618
If we take 4168 away from 4190, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 15:
The number 521 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 126602.318618
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 16:
When dividing 2200 by 521, we get 4 with a remainder of 116.
The next digit of our result is 4. 
Result so far: 126602.31861804
Subtracting 2084 from 2200 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Our division results in 126602.31861804 with a remaining 1.16e-07.
