We divide 87021057 by 45
We want to divide 87021057 by 45.

Let's proceed to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 45

Moving on to step 2:
45 can be fit into 87 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 42 after subtracting 45 from 87.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 45

On to step 3:
When dividing 420 by 45, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 405 away from 420, we end up with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 45

On to step 4:
When dividing 152 by 45, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
Deduct 135 from 152 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 45

Step 5:
171 divided by 45 is 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 1933.0
The remainder is 36 after subtracting 135 from 171.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 45

Moving on to step 6:
360 divided by 45 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 19338.0
If we take 360 away from 360, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 45

Let's proceed to step 7:
45 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 193380.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 45

Moving on to step 8:
The number 45 fits into 57 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1933801.0
The remainder is 12 after subtracting 45 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 45 is 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 1933801.2
Subtracting 90 from 120 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 45 fits into 300 6 times, leaving a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 1933801.26
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
45 goes into 300 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 1933801.266
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 1933801.266 with a balance of 0.003.
