Let's divide 69103887 by 799
Let's see how many times 799 fits into 69103887.

On to step 1:
If we divide 6 by 799, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 799

Advancing to step 2:
If we divide 69 by 799, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 69 to get 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 799

Step 3:
799 goes into 691 0 times with a remainder of 691.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 691 after subtracting 0 from 691.
Grab the next digit (0) from the dividend, add it to 691, then carry on: 6910 / 799

Let's proceed to step 4:
799 goes into 6910 8 times with a remainder of 518.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 6392 from 6910, we get 518.
Take the next digit (3) from the dividend and append it to 518, then repeat: 5183 / 799

Going ahead to step 5:
If we divide 5183 by 799, we get 6 and a remainder of 389.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 4794 from 5183 and we're left with 389.
Append the next digit (8) from the dividend to 389 and continue with: 3898 / 799

Step 6:
799 can be fit into 3898 4 times, resulting in a remainder of 702.
Record the quotient 4 as the next digit in the result. 
Result so far: 864.0
Subtracting 3196 from 3898 leaves us with 702.
Include the next digit (8) from the dividend after 702, then repeat: 7028 / 799

Going ahead to step 7:
799 goes into 7028 8 times with a remainder of 636.
The next digit of our result is 8. 
Result so far: 8648.0
If we take 6392 away from 7028, we end up with 636.
Append the next digit (7) from the dividend to 636 and continue with: 6367 / 799

On to step 8:
The number 799 fits into 6367 7 times, leaving a remainder of 774.
The number 7 becomes the next digit in our result. 
Result so far: 86487.0
The remainder is 774 after subtracting 5593 from 6367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

Let's proceed to step 9:
When dividing 7740 by 799, we get 9 with a remainder of 549.
Record the quotient 9 as the next digit in the result. 
Result so far: 86487.9
Subtract 7191 from 7740 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 10:
799 can be fit into 5490 6 times, resulting in a remainder of 696.
Use 6 as the next digit of our solution. 
Result so far: 86487.96
If we subtract 4794 from 5490, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Going ahead to step 11:
799 can be fit into 6960 8 times, resulting in a remainder of 568.
Record the quotient 8 as the next digit in the result. 
Result so far: 86487.968
Subtracting 6392 from 6960 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 12:
The number 799 fits into 5680 7 times, leaving a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 86487.9687
If we take 5593 away from 5680, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 13:
799 can be fit into 870 1 times, resulting in a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 86487.96871
Deduct 799 from 870 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 14:
If we divide 710 by 799, we get 0 and a remainder of 710.
Put 0 as the next digit of the answer. 
Result so far: 86487.96871
Deduct 0 from 710 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 15:
7100 divided by 799 is 8 with a remainder of 708.
Write down 8 as next digit of the result. 
Result so far: 86487.9687108
Subtracting 6392 from 7100 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Advancing to step 16:
799 goes into 7080 8 times with a remainder of 688.
Put 8 as the next digit of the answer. 
Result so far: 86487.96871088
If we take 6392 away from 7080, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

The quotient of the division is 86487.96871088, and the remainder is 6.88e-07.
