We look at the division of 99691891 by 403 
Let's see how many times 403 fits into 99691891.

On to step 1:
The number 403 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 403

Step 2:
When dividing 99 by 403, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 403

Let's proceed to step 3:
If we divide 996 by 403, we get 2 and a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 806 from 996 to get 190.
Bring next digit (9) of the dividend behind the 190 and repeat the process: 1909 / 403

Let's proceed to step 4:
1909 divided by 403 is 4 with a remainder of 297.
The next digit of our result is 4. 
Result so far: 24.0
Subtract 1612 from 1909 to get 297.
Include the next digit (1) from the dividend after 297, then repeat: 2971 / 403

Going ahead to step 5:
403 goes into 2971 7 times with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 247.0
If we take 2821 away from 2971, we end up with 150.
Bring next digit (8) of the dividend behind the 150 and repeat the process: 1508 / 403

Step 6:
403 goes into 1508 3 times with a remainder of 299.
Put 3 as the next digit of the answer. 
Result so far: 2473.0
If we subtract 1209 from 1508, we get 299.
Append the next digit (9) from the dividend to 299 and continue with: 2999 / 403

On to step 7:
403 goes into 2999 7 times with a remainder of 178.
Use 7 as the next digit of our solution. 
Result so far: 24737.0
Deduct 2821 from 2999 and we're left with 178.
Bring next digit (1) of the dividend behind the 178 and repeat the process: 1781 / 403

Going ahead to step 8:
403 can be fit into 1781 4 times, resulting in a remainder of 169.
The number 4 becomes the next digit in our result. 
Result so far: 247374.0
If we take 1612 away from 1781, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 9:
If we divide 1690 by 403, we get 4 and a remainder of 78.
The number 4 becomes the next digit in our result. 
Result so far: 247374.4
If we take 1612 away from 1690, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
If we divide 780 by 403, we get 1 and a remainder of 377.
Record the quotient 1 as the next digit in the result. 
Result so far: 247374.41
Subtract 403 from 780 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 11:
3770 divided by 403 is 9 with a remainder of 143.
Write down 9 as next digit of the result. 
Result so far: 247374.419
The remainder is 143 after subtracting 3627 from 3770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 12:
The number 403 fits into 1430 3 times, leaving a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 247374.4193
Subtract 1209 from 1430 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 13:
If we divide 2210 by 403, we get 5 and a remainder of 195.
The next digit of our result is 5. 
Result so far: 247374.41935
Subtract 2015 from 2210 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 14:
403 goes into 1950 4 times with a remainder of 338.
Record the quotient 4 as the next digit in the result. 
Result so far: 247374.419354
Subtracting 1612 from 1950 leaves us with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Step 15:
403 can be fit into 3380 8 times, resulting in a remainder of 156.
The next digit of our result is 8. 
Result so far: 247374.4193548
Subtracting 3224 from 3380 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 16:
When dividing 1560 by 403, we get 3 with a remainder of 351.
The next digit of our result is 3. 
Result so far: 247374.41935483
Deduct 1209 from 1560 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

The quotient of the division is 247374.41935483, and the remainder is 3.51e-07.
