We look at the division of 63510192 by 521 
Our goal is to divide 63510192 by 521.

Going ahead to step 1:
521 goes into 6 0 times with 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.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 521

On to step 2:
The number 521 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 521

Advancing to step 3:
635 divided by 521 is 1 with a remainder of 114.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 521 from 635 leaves us with 114.
Grab the next digit (1) from the dividend, add it to 114, then carry on: 1141 / 521

Advancing to step 4:
If we divide 1141 by 521, we get 2 and a remainder of 99.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 99 after subtracting 1042 from 1141.
Fetch the next digit (0) from the dividend, attach it to 99 and continue: 990 / 521

On to step 5:
990 divided by 521 is 1 with a remainder of 469.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we take 521 away from 990, we end up with 469.
Include the next digit (1) from the dividend after 469, then repeat: 4691 / 521

Going ahead to step 6:
4691 divided by 521 is 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1219.0
Deduct 4689 from 4691 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 521

Going ahead to step 7:
521 can be fit into 29 0 times, resulting in a remainder of 29.
The next digit of our result is 0. 
Result so far: 12190.0
If we take 0 away from 29, we end up with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 521

Step 8:
The number 521 fits into 292 0 times, leaving a remainder of 292.
The number 0 becomes the next digit in our result. 
Result so far: 121900.0
Deduct 0 from 292 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 9:
If we divide 2920 by 521, we get 5 and a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 121900.5
Subtract 2605 from 2920 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 10:
When dividing 3150 by 521, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 121900.56
If we subtract 3126 from 3150, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
521 goes into 240 0 times with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 121900.56
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
2400 divided by 521 is 4 with a remainder of 316.
Record the quotient 4 as the next digit in the result. 
Result so far: 121900.5604
Subtracting 2084 from 2400 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Step 13:
3160 divided by 521 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 121900.56046
Subtract 3126 from 3160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
When dividing 340 by 521, we get 0 with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 121900.56046
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 15:
When dividing 3400 by 521, we get 6 with a remainder of 274.
The number 6 becomes the next digit in our result. 
Result so far: 121900.5604606
Deduct 3126 from 3400 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Moving on to step 16:
If we divide 2740 by 521, we get 5 and a remainder of 135.
The next digit of our result is 5. 
Result so far: 121900.56046065
The remainder is 135 after subtracting 2605 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

In conclusion, the division gives 121900.56046065 with a balance of 1.35e-07.
