73698643 ÷ 523 
We want to figure out the number of times 73698643 can be divided by 523.

Step 1:
When dividing 7 by 523, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 523

Let's proceed to step 2:
When dividing 73 by 523, we get 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 523

Advancing to step 3:
If we divide 736 by 523, we get 1 and a remainder of 213.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 523 from 736 leaves us with 213.
Append the next digit (9) from the dividend to 213 and continue with: 2139 / 523

Going ahead to step 4:
If we divide 2139 by 523, we get 4 and a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2092 away from 2139, we end up with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 523

Moving on to step 5:
When dividing 478 by 523, we get 0 with a remainder of 478.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
The remainder is 478 after subtracting 0 from 478.
Append the next digit (6) from the dividend to 478 and continue with: 4786 / 523

Step 6:
523 can be fit into 4786 9 times, resulting in a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 1409.0
Subtract 4707 from 4786 to get 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 523

Advancing to step 7:
When dividing 794 by 523, we get 1 with a remainder of 271.
The next digit of our result is 1. 
Result so far: 14091.0
The remainder is 271 after subtracting 523 from 794.
Take the next digit (3) from the dividend and append it to 271, then repeat: 2713 / 523

Step 8:
2713 divided by 523 is 5 with a remainder of 98.
The number 5 becomes the next digit in our result. 
Result so far: 140915.0
Subtracting 2615 from 2713 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 9:
980 divided by 523 is 1 with a remainder of 457.
Write down 1 as next digit of the result. 
Result so far: 140915.1
The remainder is 457 after subtracting 523 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 10:
523 can be fit into 4570 8 times, resulting in a remainder of 386.
Put 8 as the next digit of the answer. 
Result so far: 140915.18
Subtract 4184 from 4570 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 11:
523 goes into 3860 7 times with a remainder of 199.
Write down 7 as next digit of the result. 
Result so far: 140915.187
If we subtract 3661 from 3860, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 12:
When dividing 1990 by 523, we get 3 with a remainder of 421.
The next digit of our result is 3. 
Result so far: 140915.1873
If we subtract 1569 from 1990, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 13:
4210 divided by 523 is 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 140915.18738
If we subtract 4184 from 4210, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
If we divide 260 by 523, we get 0 and a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 140915.18738
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 15:
If we divide 2600 by 523, we get 4 and a remainder of 508.
Use 4 as the next digit of our solution. 
Result so far: 140915.1873804
If we subtract 2092 from 2600, we get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 16:
The number 523 fits into 5080 9 times, leaving a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 140915.18738049
Deduct 4707 from 5080 and we're left with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

The final result is 140915.18738049 with a remainder of 3.73e-07.
