97800130 ÷ 520 
We want to figure out the number of times 97800130 can be divided by 520.

Advancing to step 1:
9 divided by 520 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 520

On to step 2:
97 divided by 520 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Take the next digit (8) from the dividend and append it to 97, then repeat: 978 / 520

Going ahead to step 3:
978 divided by 520 is 1 with a remainder of 458.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 520 from 978 to get 458.
Grab the next digit (0) from the dividend, add it to 458, then carry on: 4580 / 520

On to step 4:
The number 520 fits into 4580 8 times, leaving a remainder of 420.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 4160 from 4580 and we're left with 420.
Fetch the next digit (0) from the dividend, attach it to 420 and continue: 4200 / 520

Advancing to step 5:
The number 520 fits into 4200 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 188.0
Subtracting 4160 from 4200 leaves us with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 520

Let's proceed to step 6:
If we divide 401 by 520, we get 0 and a remainder of 401.
Use 0 as the next digit of our solution. 
Result so far: 1880.0
Subtract 0 from 401 to get 401.
Grab the next digit (3) from the dividend, add it to 401, then carry on: 4013 / 520

Step 7:
When dividing 4013 by 520, we get 7 with a remainder of 373.
Write down 7 as next digit of the result. 
Result so far: 18807.0
If we take 3640 away from 4013, we end up with 373.
Fetch the next digit (0) from the dividend, attach it to 373 and continue: 3730 / 520

Step 8:
3730 divided by 520 is 7 with a remainder of 90.
Put 7 as the next digit of the answer. 
Result so far: 188077.0
If we take 3640 away from 3730, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
520 goes into 900 1 times with a remainder of 380.
Put 1 as the next digit of the answer. 
Result so far: 188077.1
If we take 520 away from 900, we end up with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 10:
When dividing 3800 by 520, we get 7 with a remainder of 160.
Put 7 as the next digit of the answer. 
Result so far: 188077.17
Subtract 3640 from 3800 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.

Advancing to step 11:
When dividing 1600 by 520, we get 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 188077.173
Subtract 1560 from 1600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
When dividing 400 by 520, we get 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 188077.173
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
520 can be fit into 4000 7 times, resulting in a remainder of 360.
Put 7 as the next digit of the answer. 
Result so far: 188077.17307
Deduct 3640 from 4000 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 14:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 188077.173076
If we subtract 3120 from 3600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 15:
The number 520 fits into 4800 9 times, leaving a remainder of 120.
The number 9 becomes the next digit in our result. 
Result so far: 188077.1730769
If we subtract 4680 from 4800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 16:
When dividing 1200 by 520, we get 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 188077.17307692
Subtracting 1040 from 1200 leaves us 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.

Our division results in 188077.17307692 with a remaining 1.6e-07.
