We look at the division of 45570789 by 511 
We want to divide 45570789 by 511.

Let's proceed to step 1:
The number 511 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 511

On to step 2:
When dividing 45 by 511, we get 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 511

Moving on to step 3:
If we divide 455 by 511, we get 0 and a remainder of 455.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 455 and we're left with 455.
Take the next digit (7) from the dividend and append it to 455, then repeat: 4557 / 511

Going ahead to step 4:
4557 divided by 511 is 8 with a remainder of 469.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 4088 from 4557 and we're left with 469.
Append the next digit (0) from the dividend to 469 and continue with: 4690 / 511

Moving on to step 5:
When dividing 4690 by 511, we get 9 with a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Deduct 4599 from 4690 and we're left with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 511

Advancing to step 6:
917 divided by 511 is 1 with a remainder of 406.
Use 1 as the next digit of our solution. 
Result so far: 891.0
Subtracting 511 from 917 leaves us with 406.
Bring next digit (8) of the dividend behind the 406 and repeat the process: 4068 / 511

Moving on to step 7:
511 goes into 4068 7 times with a remainder of 491.
Write down 7 as next digit of the result. 
Result so far: 8917.0
Subtracting 3577 from 4068 leaves us with 491.
Take the next digit (9) from the dividend and append it to 491, then repeat: 4919 / 511

Let's proceed to step 8:
4919 divided by 511 is 9 with a remainder of 320.
Put 9 as the next digit of the answer. 
Result so far: 89179.0
Subtracting 4599 from 4919 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 9:
3200 divided by 511 is 6 with a remainder of 134.
Write down 6 as next digit of the result. 
Result so far: 89179.6
Deduct 3066 from 3200 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
511 can be fit into 1340 2 times, resulting in a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 89179.62
Deduct 1022 from 1340 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 11:
511 can be fit into 3180 6 times, resulting in a remainder of 114.
The next digit of our result is 6. 
Result so far: 89179.626
Subtract 3066 from 3180 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 12:
1140 divided by 511 is 2 with a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 89179.6262
If we subtract 1022 from 1140, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 13:
511 can be fit into 1180 2 times, resulting in a remainder of 158.
The next digit of our result is 2. 
Result so far: 89179.62622
If we subtract 1022 from 1180, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The quotient of the division is 89179.62622, and the remainder is 0.000158.
