We divide 869624 by 70
We're looking to find how many times 70 goes into 869624.

Going ahead to step 1:
70 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 70

On to step 2:
70 can be fit into 86 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 70 from 86 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 70

Let's proceed to step 3:
If we divide 169 by 70, we get 2 and a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 140 from 169 to get 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 70

Advancing to step 4:
70 goes into 296 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 124.0
Subtract 280 from 296 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 70

Advancing to step 5:
70 can be fit into 162 2 times, resulting in a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 1242.0
Deduct 140 from 162 and we're left with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 70

Let's proceed to step 6:
If we divide 224 by 70, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 12423.0
If we subtract 210 from 224, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
The number 70 fits into 140 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12423.2
Deduct 140 from 140 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 70, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12423.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
70 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12423.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 12423.2 and a remainder of 0.0.
