We're dividing 70985509 by 438 
Let's see how many times 438 fits into 70985509.

Step 1:
7 divided by 438 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 438

On to step 2:
438 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 438

Step 3:
709 divided by 438 is 1 with a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 271 after subtracting 438 from 709.
Bring next digit (8) of the dividend behind the 271 and repeat the process: 2718 / 438

Moving on to step 4:
The number 438 fits into 2718 6 times, leaving a remainder of 90.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2628 from 2718 to get 90.
Append the next digit (5) from the dividend to 90 and continue with: 905 / 438

Let's proceed to step 5:
438 can be fit into 905 2 times, resulting in a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Deduct 876 from 905 and we're left with 29.
Grab the next digit (5) from the dividend, add it to 29, then carry on: 295 / 438

On to step 6:
The number 438 fits into 295 0 times, leaving a remainder of 295.
The number 0 becomes the next digit in our result. 
Result so far: 1620.0
If we subtract 0 from 295, we get 295.
Take the next digit (0) from the dividend and append it to 295, then repeat: 2950 / 438

Let's proceed to step 7:
If we divide 2950 by 438, we get 6 and a remainder of 322.
The number 6 becomes the next digit in our result. 
Result so far: 16206.0
If we take 2628 away from 2950, we end up with 322.
Include the next digit (9) from the dividend after 322, then repeat: 3229 / 438

Let's proceed to step 8:
When dividing 3229 by 438, we get 7 with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 162067.0
Subtracting 3066 from 3229 leaves us with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 9:
If we divide 1630 by 438, we get 3 and a remainder of 316.
The number 3 becomes the next digit in our result. 
Result so far: 162067.3
The remainder is 316 after subtracting 1314 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 10:
When dividing 3160 by 438, we get 7 with a remainder of 94.
The next digit of our result is 7. 
Result so far: 162067.37
If we subtract 3066 from 3160, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 11:
940 divided by 438 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 162067.372
Subtract 876 from 940 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
When dividing 640 by 438, we get 1 with a remainder of 202.
Write down 1 as next digit of the result. 
Result so far: 162067.3721
Deduct 438 from 640 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 13:
2020 divided by 438 is 4 with a remainder of 268.
Put 4 as the next digit of the answer. 
Result so far: 162067.37214
Subtract 1752 from 2020 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 14:
The number 438 fits into 2680 6 times, leaving a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 162067.372146
Subtracting 2628 from 2680 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 15:
520 divided by 438 is 1 with a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 162067.3721461
Subtract 438 from 520 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 16:
If we divide 820 by 438, we get 1 and a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 162067.37214611
Subtract 438 from 820 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

After the division, we end up with 162067.37214611 and a remainder of 3.82e-07.
