Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 870

Advancing to step 2:
45 divided by 870 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 870

Step 3:
870 goes into 454 0 times with a remainder of 454.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 454 leaves us with 454.
Grab the next digit (5) from the dividend, add it to 454, then carry on: 4545 / 870

Advancing to step 4:
The number 870 fits into 4545 5 times, leaving a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 195 after subtracting 4350 from 4545.
Fetch the next digit (4) from the dividend, attach it to 195 and continue: 1954 / 870

Going ahead to step 5:
1954 divided by 870 is 2 with a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 1740 away from 1954, we end up with 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 870

On to step 6:
870 goes into 2145 2 times with a remainder of 405.
The number 2 becomes the next digit in our result. 
Result so far: 522.0
The remainder is 405 after subtracting 1740 from 2145.
Append the next digit (2) from the dividend to 405 and continue with: 4052 / 870

On to step 7:
870 goes into 4052 4 times with a remainder of 572.
Record the quotient 4 as the next digit in the result. 
Result so far: 5224.0
If we subtract 3480 from 4052, we get 572.
Grab the next digit (4) from the dividend, add it to 572, then carry on: 5724 / 870

Step 8:
The number 870 fits into 5724 6 times, leaving a remainder of 504.
The next digit of our result is 6. 
Result so far: 52246.0
Subtract 5220 from 5724 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 9:
If we divide 5040 by 870, we get 5 and a remainder of 690.
Use 5 as the next digit of our solution. 
Result so far: 52246.5
If we subtract 4350 from 5040, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 10:
When dividing 6900 by 870, we get 7 with a remainder of 810.
Use 7 as the next digit of our solution. 
Result so far: 52246.57
If we subtract 6090 from 6900, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Let's proceed to step 11:
When dividing 8100 by 870, we get 9 with a remainder of 270.
Put 9 as the next digit of the answer. 
Result so far: 52246.579
If we subtract 7830 from 8100, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 12:
The number 870 fits into 2700 3 times, leaving a remainder of 90.
Write down 3 as next digit of the result. 
Result so far: 52246.5793
Deduct 2610 from 2700 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
The number 870 fits into 900 1 times, leaving a remainder of 30.
The next digit of our result is 1. 
Result so far: 52246.57931
Subtract 870 from 900 to 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.

On to step 14:
870 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 52246.57931
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
870 goes into 3000 3 times with a remainder of 390.
Put 3 as the next digit of the answer. 
Result so far: 52246.5793103
Subtracting 2610 from 3000 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 16:
The number 870 fits into 3900 4 times, leaving a remainder of 420.
Write down 4 as next digit of the result. 
Result so far: 52246.57931034
Subtracting 3480 from 3900 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 52246.57931034 with a balance of 4.2e-07.
