We look at the division of 75686473 by 45 
We want to divide 75686473 by 45.

Moving on to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 45

Going ahead to step 2:
45 can be fit into 75 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 75 and we're left with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 45

Let's proceed to step 3:
45 goes into 306 6 times with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 270 from 306 leaves us with 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 45

Let's proceed to step 4:
368 divided by 45 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 168.0
The remainder is 8 after subtracting 360 from 368.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 45

Going ahead to step 5:
The number 45 fits into 86 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 1681.0
Subtracting 45 from 86 leaves us with 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 45

Let's proceed to step 6:
If we divide 414 by 45, we get 9 and a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 16819.0
Subtracting 405 from 414 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 45

Going ahead to step 7:
When dividing 97 by 45, we get 2 with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 168192.0
If we take 90 away from 97, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 45

Advancing to step 8:
When dividing 73 by 45, we get 1 with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1681921.0
If we take 45 away from 73, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
When dividing 280 by 45, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1681921.6
The remainder is 10 after subtracting 270 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
45 goes into 100 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 1681921.62
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
100 divided by 45 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 1681921.622
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1681921.622, and the remainder is 0.001.
