22455120 ÷ 870 
We want to figure out the number of times 22455120 can be divided by 870.

On to step 1:
If we divide 2 by 870, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 870

Going ahead to step 2:
870 can be fit into 22 0 times, resulting in a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 870

Step 3:
If we divide 224 by 870, we get 0 and a remainder of 224.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 224, we end up with 224.
Grab the next digit (5) from the dividend, add it to 224, then carry on: 2245 / 870

Going ahead to step 4:
2245 divided by 870 is 2 with a remainder of 505.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1740 from 2245 and we're left with 505.
Append the next digit (5) from the dividend to 505 and continue with: 5055 / 870

Going ahead to step 5:
870 goes into 5055 5 times with a remainder of 705.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 705 after subtracting 4350 from 5055.
Take the next digit (1) from the dividend and append it to 705, then repeat: 7051 / 870

Advancing to step 6:
870 goes into 7051 8 times with a remainder of 91.
The next digit of our result is 8. 
Result so far: 258.0
Subtract 6960 from 7051 to get 91.
Grab the next digit (2) from the dividend, add it to 91, then carry on: 912 / 870

Let's proceed to step 7:
When dividing 912 by 870, we get 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 2581.0
Subtract 870 from 912 to get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 870

Let's proceed to step 8:
When dividing 420 by 870, we get 0 with a remainder of 420.
Record the quotient 0 as the next digit in the result. 
Result so far: 25810.0
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 9:
If we divide 4200 by 870, we get 4 and a remainder of 720.
Put 4 as the next digit of the answer. 
Result so far: 25810.4
If we take 3480 away from 4200, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 10:
870 goes into 7200 8 times with a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 25810.48
If we subtract 6960 from 7200, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
If we divide 2400 by 870, we get 2 and a remainder of 660.
Put 2 as the next digit of the answer. 
Result so far: 25810.482
If we subtract 1740 from 2400, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 12:
The number 870 fits into 6600 7 times, leaving a remainder of 510.
Use 7 as the next digit of our solution. 
Result so far: 25810.4827
The remainder is 510 after subtracting 6090 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Step 13:
870 can be fit into 5100 5 times, resulting in a remainder of 750.
Record the quotient 5 as the next digit in the result. 
Result so far: 25810.48275
Subtracting 4350 from 5100 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 14:
7500 divided by 870 is 8 with a remainder of 540.
Put 8 as the next digit of the answer. 
Result so far: 25810.482758
Subtract 6960 from 7500 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
When dividing 5400 by 870, we get 6 with a remainder of 180.
Write down 6 as next digit of the result. 
Result so far: 25810.4827586
Subtracting 5220 from 5400 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 16:
870 can be fit into 1800 2 times, resulting in a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 25810.48275862
Subtract 1740 from 1800 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 25810.48275862 with a balance of 6e-08.
