45645433 ÷ 878 
We want to figure out the number of times 45645433 can be divided by 878.

Advancing to step 1:
4 divided by 878 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 878

Step 2:
When dividing 45 by 878, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (6) of the dividend behind the 45 and repeat the process: 456 / 878

Moving on to step 3:
The number 878 fits into 456 0 times, leaving a remainder of 456.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 456, we end up with 456.
Bring next digit (4) of the dividend behind the 456 and repeat the process: 4564 / 878

Moving on to step 4:
When dividing 4564 by 878, we get 5 with a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4390 from 4564 and we're left with 174.
Append the next digit (5) from the dividend to 174 and continue with: 1745 / 878

Let's proceed to step 5:
878 goes into 1745 1 times with a remainder of 867.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 878 from 1745, we get 867.
Bring next digit (4) of the dividend behind the 867 and repeat the process: 8674 / 878

Advancing to step 6:
When dividing 8674 by 878, we get 9 with a remainder of 772.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
If we take 7902 away from 8674, we end up with 772.
Bring next digit (3) of the dividend behind the 772 and repeat the process: 7723 / 878

Moving on to step 7:
When dividing 7723 by 878, we get 8 with a remainder of 699.
The number 8 becomes the next digit in our result. 
Result so far: 5198.0
The remainder is 699 after subtracting 7024 from 7723.
Append the next digit (3) from the dividend to 699 and continue with: 6993 / 878

Let's proceed to step 8:
If we divide 6993 by 878, we get 7 and a remainder of 847.
Write down 7 as next digit of the result. 
Result so far: 51987.0
Subtracting 6146 from 6993 leaves us with 847.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8470, and continue the process.

Going ahead to step 9:
878 can be fit into 8470 9 times, resulting in a remainder of 568.
Put 9 as the next digit of the answer. 
Result so far: 51987.9
Subtracting 7902 from 8470 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 10:
878 goes into 5680 6 times with a remainder of 412.
Put 6 as the next digit of the answer. 
Result so far: 51987.96
If we subtract 5268 from 5680, we get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 11:
878 goes into 4120 4 times with a remainder of 608.
Write down 4 as next digit of the result. 
Result so far: 51987.964
Subtract 3512 from 4120 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 12:
If we divide 6080 by 878, we get 6 and a remainder of 812.
The number 6 becomes the next digit in our result. 
Result so far: 51987.9646
Deduct 5268 from 6080 and we're left with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Let's proceed to step 13:
878 goes into 8120 9 times with a remainder of 218.
Record the quotient 9 as the next digit in the result. 
Result so far: 51987.96469
If we take 7902 away from 8120, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 14:
When dividing 2180 by 878, we get 2 with a remainder of 424.
Record the quotient 2 as the next digit in the result. 
Result so far: 51987.964692
The remainder is 424 after subtracting 1756 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 15:
878 can be fit into 4240 4 times, resulting in a remainder of 728.
Record the quotient 4 as the next digit in the result. 
Result so far: 51987.9646924
The remainder is 728 after subtracting 3512 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Advancing to step 16:
The number 878 fits into 7280 8 times, leaving a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 51987.96469248
Deduct 7024 from 7280 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 51987.96469248 and a remainder of 2.56e-07.
