775970 divided by 45 
Our goal is to divide 775970 by 45.

On to step 1:
45 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 45

Advancing to step 2:
45 goes into 77 1 times with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 77 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 45

Going ahead to step 3:
45 can be fit into 325 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 315 away from 325, we end up with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 45

Step 4:
45 goes into 109 2 times with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 172.0
If we subtract 90 from 109, we get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 45

On to step 5:
If we divide 197 by 45, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 1724.0
Subtracting 180 from 197 leaves us with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 45

Let's proceed to step 6:
When dividing 170 by 45, we get 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 17243.0
If we subtract 135 from 170, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 17243.7
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 17243.77
Deduct 315 from 350 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 17243.77 with a remaining 0.035.
