We're dividing 70916321 by 549 
We want to figure out the number of times 70916321 can be divided by 549.

Let's proceed to step 1:
If we divide 7 by 549, we get 0 and 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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 549

Let's proceed to step 2:
If we divide 70 by 549, we get 0 and 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.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 549

Step 3:
The number 549 fits into 709 1 times, leaving a remainder of 160.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 160 after subtracting 549 from 709.
Include the next digit (1) from the dividend after 160, then repeat: 1601 / 549

Moving on to step 4:
549 goes into 1601 2 times with a remainder of 503.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1098 from 1601, we get 503.
Bring next digit (6) of the dividend behind the 503 and repeat the process: 5036 / 549

Let's proceed to step 5:
5036 divided by 549 is 9 with a remainder of 95.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 4941 from 5036 to get 95.
Include the next digit (3) from the dividend after 95, then repeat: 953 / 549

Going ahead to step 6:
If we divide 953 by 549, we get 1 and a remainder of 404.
Put 1 as the next digit of the answer. 
Result so far: 1291.0
Subtract 549 from 953 to get 404.
Append the next digit (2) from the dividend to 404 and continue with: 4042 / 549

Going ahead to step 7:
If we divide 4042 by 549, we get 7 and a remainder of 199.
Use 7 as the next digit of our solution. 
Result so far: 12917.0
The remainder is 199 after subtracting 3843 from 4042.
Bring next digit (1) of the dividend behind the 199 and repeat the process: 1991 / 549

Moving on to step 8:
549 can be fit into 1991 3 times, resulting in a remainder of 344.
The number 3 becomes the next digit in our result. 
Result so far: 129173.0
Subtract 1647 from 1991 to get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 9:
549 goes into 3440 6 times with a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 129173.6
The remainder is 146 after subtracting 3294 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 10:
When dividing 1460 by 549, we get 2 with a remainder of 362.
The number 2 becomes the next digit in our result. 
Result so far: 129173.62
Deduct 1098 from 1460 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 11:
The number 549 fits into 3620 6 times, leaving a remainder of 326.
The next digit of our result is 6. 
Result so far: 129173.626
If we take 3294 away from 3620, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 12:
3260 divided by 549 is 5 with a remainder of 515.
Use 5 as the next digit of our solution. 
Result so far: 129173.6265
Subtract 2745 from 3260 to get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

On to step 13:
549 can be fit into 5150 9 times, resulting in a remainder of 209.
Write down 9 as next digit of the result. 
Result so far: 129173.62659
If we subtract 4941 from 5150, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 14:
If we divide 2090 by 549, we get 3 and a remainder of 443.
Record the quotient 3 as the next digit in the result. 
Result so far: 129173.626593
Deduct 1647 from 2090 and we're left with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Moving on to step 15:
If we divide 4430 by 549, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 129173.6265938
Deduct 4392 from 4430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 16:
If we divide 380 by 549, we get 0 and a remainder of 380.
Put 0 as the next digit of the answer. 
Result so far: 129173.6265938
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Our division results in 129173.6265938 with a remaining 3.8e-07.
