Let's divide 80351918 by 511
We're looking to find how many times 511 goes into 80351918.

Moving on to step 1:
511 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 511

Advancing to step 2:
If we divide 80 by 511, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 511

Moving on to step 3:
The number 511 fits into 803 1 times, leaving a remainder of 292.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 511 from 803 and we're left with 292.
Append the next digit (5) from the dividend to 292 and continue with: 2925 / 511

Let's proceed to step 4:
When dividing 2925 by 511, we get 5 with a remainder of 370.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 2555 away from 2925, we end up with 370.
Include the next digit (1) from the dividend after 370, then repeat: 3701 / 511

Advancing to step 5:
If we divide 3701 by 511, we get 7 and a remainder of 124.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Subtracting 3577 from 3701 leaves us with 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 511

Let's proceed to step 6:
511 goes into 1249 2 times with a remainder of 227.
Put 2 as the next digit of the answer. 
Result so far: 1572.0
Subtract 1022 from 1249 to get 227.
Append the next digit (1) from the dividend to 227 and continue with: 2271 / 511

On to step 7:
The number 511 fits into 2271 4 times, leaving a remainder of 227.
Record the quotient 4 as the next digit in the result. 
Result so far: 15724.0
The remainder is 227 after subtracting 2044 from 2271.
Take the next digit (8) from the dividend and append it to 227, then repeat: 2278 / 511

Advancing to step 8:
511 can be fit into 2278 4 times, resulting in a remainder of 234.
The number 4 becomes the next digit in our result. 
Result so far: 157244.0
Subtract 2044 from 2278 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
511 goes into 2340 4 times with a remainder of 296.
Write down 4 as next digit of the result. 
Result so far: 157244.4
If we subtract 2044 from 2340, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 10:
2960 divided by 511 is 5 with a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 157244.45
The remainder is 405 after subtracting 2555 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 11:
If we divide 4050 by 511, we get 7 and a remainder of 473.
Use 7 as the next digit of our solution. 
Result so far: 157244.457
Subtracting 3577 from 4050 leaves us with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 12:
4730 divided by 511 is 9 with a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 157244.4579
If we subtract 4599 from 4730, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 13:
If we divide 1310 by 511, we get 2 and a remainder of 288.
Put 2 as the next digit of the answer. 
Result so far: 157244.45792
If we subtract 1022 from 1310, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 14:
511 goes into 2880 5 times with a remainder of 325.
The next digit of our result is 5. 
Result so far: 157244.457925
Subtract 2555 from 2880 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 15:
If we divide 3250 by 511, we get 6 and a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 157244.4579256
The remainder is 184 after subtracting 3066 from 3250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
If we divide 1840 by 511, we get 3 and a remainder of 307.
Put 3 as the next digit of the answer. 
Result so far: 157244.45792563
Deduct 1533 from 1840 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

The final outcome is 157244.45792563, with a leftover of 3.07e-07.
