We look at the division of 73515757 by 820 
We're looking to find how many times 820 goes into 73515757.

Step 1:
The number 820 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 820

Let's proceed to step 2:
The number 820 fits into 73 0 times, leaving a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 820

Step 3:
If we divide 735 by 820, we get 0 and a remainder of 735.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 735 and we're left with 735.
Fetch the next digit (1) from the dividend, attach it to 735 and continue: 7351 / 820

Moving on to step 4:
The number 820 fits into 7351 8 times, leaving a remainder of 791.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6560 from 7351 to get 791.
Include the next digit (5) from the dividend after 791, then repeat: 7915 / 820

Let's proceed to step 5:
820 can be fit into 7915 9 times, resulting in a remainder of 535.
Write down 9 as next digit of the result. 
Result so far: 89.0
If we subtract 7380 from 7915, we get 535.
Grab the next digit (7) from the dividend, add it to 535, then carry on: 5357 / 820

Going ahead to step 6:
820 goes into 5357 6 times with a remainder of 437.
Put 6 as the next digit of the answer. 
Result so far: 896.0
Subtracting 4920 from 5357 leaves us with 437.
Include the next digit (5) from the dividend after 437, then repeat: 4375 / 820

Advancing to step 7:
When dividing 4375 by 820, we get 5 with a remainder of 275.
Record the quotient 5 as the next digit in the result. 
Result so far: 8965.0
The remainder is 275 after subtracting 4100 from 4375.
Bring next digit (7) of the dividend behind the 275 and repeat the process: 2757 / 820

Moving on to step 8:
If we divide 2757 by 820, we get 3 and a remainder of 297.
Put 3 as the next digit of the answer. 
Result so far: 89653.0
If we subtract 2460 from 2757, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 9:
820 goes into 2970 3 times with a remainder of 510.
Write down 3 as next digit of the result. 
Result so far: 89653.3
The remainder is 510 after subtracting 2460 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 10:
The number 820 fits into 5100 6 times, leaving a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 89653.36
If we subtract 4920 from 5100, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
The number 820 fits into 1800 2 times, leaving a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 89653.362
If we take 1640 away from 1800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
When dividing 1600 by 820, we get 1 with a remainder of 780.
The next digit of our result is 1. 
Result so far: 89653.3621
If we take 820 away from 1600, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

On to step 13:
If we divide 7800 by 820, we get 9 and a remainder of 420.
Write down 9 as next digit of the result. 
Result so far: 89653.36219
Subtract 7380 from 7800 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 14:
When dividing 4200 by 820, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 89653.362195
If we subtract 4100 from 4200, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 15:
820 can be fit into 1000 1 times, resulting in a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 89653.3621951
Subtract 820 from 1000 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 16:
When dividing 1800 by 820, we get 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 89653.36219512
Subtract 1640 from 1800 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 89653.36219512 with a remaining 1.6e-07.
