We look at the division of 65699308 by 521 
We're looking to find how many times 521 goes into 65699308.

Advancing to step 1:
521 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 521

Going ahead to step 2:
The number 521 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 521

Let's proceed to step 3:
If we divide 656 by 521, we get 1 and a remainder of 135.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 521 from 656 to get 135.
Bring next digit (9) of the dividend behind the 135 and repeat the process: 1359 / 521

Step 4:
521 can be fit into 1359 2 times, resulting in a remainder of 317.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1042 from 1359, we get 317.
Grab the next digit (9) from the dividend, add it to 317, then carry on: 3179 / 521

Let's proceed to step 5:
When dividing 3179 by 521, we get 6 with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 3126 away from 3179, we end up with 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 521

Advancing to step 6:
521 can be fit into 533 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1261.0
Deduct 521 from 533 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 521

Advancing to step 7:
If we divide 120 by 521, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 12610.0
If we subtract 0 from 120, we get 120.
Grab the next digit (8) from the dividend, add it to 120, then carry on: 1208 / 521

Advancing to step 8:
1208 divided by 521 is 2 with a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 126102.0
If we subtract 1042 from 1208, we 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.

Advancing to step 9:
If we divide 1660 by 521, we get 3 and a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 126102.3
If we subtract 1563 from 1660, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 10:
521 can be fit into 970 1 times, resulting in a remainder of 449.
Use 1 as the next digit of our solution. 
Result so far: 126102.31
The remainder is 449 after subtracting 521 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Going ahead 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: 126102.318
Subtract 4168 from 4490 to get 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:
521 can be fit into 3220 6 times, resulting in a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 126102.3186
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.

Advancing to step 13:
If we divide 940 by 521, we get 1 and a remainder of 419.
Record the quotient 1 as the next digit in the result. 
Result so far: 126102.31861
Subtracting 521 from 940 leaves us 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.

Advancing to step 14:
When dividing 4190 by 521, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 126102.318618
Deduct 4168 from 4190 and we're left 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.

Going ahead to step 15:
The number 521 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 126102.318618
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.

Let's proceed to step 16:
The number 521 fits into 2200 4 times, leaving a remainder of 116.
The next digit of our result is 4. 
Result so far: 126102.31861804
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.

The final outcome is 126102.31861804, with a leftover of 1.16e-07.
