99624400 ÷ 870 
Let's see how many times 870 fits into 99624400.

Advancing to step 1:
If we divide 9 by 870, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 870

Going ahead to step 2:
The number 870 fits into 99 0 times, leaving a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 870

On to step 3:
If we divide 996 by 870, we get 1 and a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 870 from 996 leaves us with 126.
Include the next digit (2) from the dividend after 126, then repeat: 1262 / 870

Going ahead to step 4:
870 can be fit into 1262 1 times, resulting in a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 870 from 1262 and we're left with 392.
Bring next digit (4) of the dividend behind the 392 and repeat the process: 3924 / 870

Let's proceed to step 5:
3924 divided by 870 is 4 with a remainder of 444.
Write down 4 as next digit of the result. 
Result so far: 114.0
Subtracting 3480 from 3924 leaves us with 444.
Include the next digit (4) from the dividend after 444, then repeat: 4444 / 870

Going ahead to step 6:
The number 870 fits into 4444 5 times, leaving a remainder of 94.
Use 5 as the next digit of our solution. 
Result so far: 1145.0
Subtracting 4350 from 4444 leaves us with 94.
Bring next digit (0) of the dividend behind the 94 and repeat the process: 940 / 870

Step 7:
When dividing 940 by 870, we get 1 with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 11451.0
Deduct 870 from 940 and we're left with 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 870

Advancing to step 8:
If we divide 700 by 870, we get 0 and a remainder of 700.
The next digit of our result is 0. 
Result so far: 114510.0
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 9:
7000 divided by 870 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 114510.8
If we subtract 6960 from 7000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 870, we get 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 114510.8
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
4000 divided by 870 is 4 with a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 114510.804
The remainder is 520 after subtracting 3480 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
5200 divided by 870 is 5 with a remainder of 850.
Put 5 as the next digit of the answer. 
Result so far: 114510.8045
Subtracting 4350 from 5200 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

On to step 13:
870 can be fit into 8500 9 times, resulting in a remainder of 670.
Use 9 as the next digit of our solution. 
Result so far: 114510.80459
If we take 7830 away from 8500, we end up with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 14:
870 can be fit into 6700 7 times, resulting in a remainder of 610.
The number 7 becomes the next digit in our result. 
Result so far: 114510.804597
Deduct 6090 from 6700 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 15:
6100 divided by 870 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 114510.8045977
Subtracting 6090 from 6100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 114510.8045977 with a remaining 1e-07.
