We divide 80195889 by 520
Let's see how many times 520 fits into 80195889.

Moving on to step 1:
The number 520 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 520

Advancing to step 2:
The number 520 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 520

On to step 3:
When dividing 801 by 520, we get 1 with a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 520 from 801 and we're left with 281.
Grab the next digit (9) from the dividend, add it to 281, then carry on: 2819 / 520

Step 4:
520 can be fit into 2819 5 times, resulting in a remainder of 219.
The next digit of our result is 5. 
Result so far: 15.0
Deduct 2600 from 2819 and we're left with 219.
Fetch the next digit (5) from the dividend, attach it to 219 and continue: 2195 / 520

On to step 5:
When dividing 2195 by 520, we get 4 with a remainder of 115.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Subtracting 2080 from 2195 leaves us with 115.
Fetch the next digit (8) from the dividend, attach it to 115 and continue: 1158 / 520

Going ahead to step 6:
The number 520 fits into 1158 2 times, leaving a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 1542.0
If we take 1040 away from 1158, we end up with 118.
Take the next digit (8) from the dividend and append it to 118, then repeat: 1188 / 520

Let's proceed to step 7:
If we divide 1188 by 520, we get 2 and a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 15422.0
Subtracting 1040 from 1188 leaves us with 148.
Bring next digit (9) of the dividend behind the 148 and repeat the process: 1489 / 520

Advancing to step 8:
When dividing 1489 by 520, we get 2 with a remainder of 449.
The next digit of our result is 2. 
Result so far: 154222.0
The remainder is 449 after subtracting 1040 from 1489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 9:
The number 520 fits into 4490 8 times, leaving a remainder of 330.
Use 8 as the next digit of our solution. 
Result so far: 154222.8
Deduct 4160 from 4490 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
520 goes into 3300 6 times with a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 154222.86
If we take 3120 away from 3300, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
When dividing 1800 by 520, we get 3 with a remainder of 240.
Use 3 as the next digit of our solution. 
Result so far: 154222.863
Subtracting 1560 from 1800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
If we divide 2400 by 520, we get 4 and a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 154222.8634
If we subtract 2080 from 2400, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 13:
520 goes into 3200 6 times with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 154222.86346
If we subtract 3120 from 3200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
If we divide 800 by 520, we get 1 and a remainder of 280.
The next digit of our result is 1. 
Result so far: 154222.863461
If we take 520 away from 800, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
520 can be fit into 2800 5 times, resulting in a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 154222.8634615
The remainder is 200 after subtracting 2600 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 16:
2000 divided by 520 is 3 with a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 154222.86346153
The remainder is 440 after subtracting 1560 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 154222.86346153, with a leftover of 4.4e-07.
