78706811 ÷ 403 
We want to divide 78706811 by 403.

Going ahead to step 1:
When dividing 7 by 403, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 403

Step 2:
78 divided by 403 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 403

Let's proceed to step 3:
787 divided by 403 is 1 with a remainder of 384.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 384 after subtracting 403 from 787.
Include the next digit (0) from the dividend after 384, then repeat: 3840 / 403

Step 4:
If we divide 3840 by 403, we get 9 and a remainder of 213.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 3627 from 3840 leaves us with 213.
Take the next digit (6) from the dividend and append it to 213, then repeat: 2136 / 403

Advancing to step 5:
The number 403 fits into 2136 5 times, leaving a remainder of 121.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
If we subtract 2015 from 2136, we get 121.
Include the next digit (8) from the dividend after 121, then repeat: 1218 / 403

Step 6:
1218 divided by 403 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 1953.0
Deduct 1209 from 1218 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 403

Moving on to step 7:
403 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 19530.0
The remainder is 91 after subtracting 0 from 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 403

Going ahead to step 8:
403 can be fit into 911 2 times, resulting in a remainder of 105.
The next digit of our result is 2. 
Result so far: 195302.0
If we subtract 806 from 911, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
The number 403 fits into 1050 2 times, leaving a remainder of 244.
Write down 2 as next digit of the result. 
Result so far: 195302.2
Subtract 806 from 1050 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 10:
403 goes into 2440 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 195302.26
If we take 2418 away from 2440, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
If we divide 220 by 403, we get 0 and a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 195302.26
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
The number 403 fits into 2200 5 times, leaving a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 195302.2605
If we subtract 2015 from 2200, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 13:
If we divide 1850 by 403, we get 4 and a remainder of 238.
The number 4 becomes the next digit in our result. 
Result so far: 195302.26054
If we subtract 1612 from 1850, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 14:
2380 divided by 403 is 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 195302.260545
Subtracting 2015 from 2380 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 15:
The number 403 fits into 3650 9 times, leaving a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 195302.2605459
Deduct 3627 from 3650 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 16:
When dividing 230 by 403, we get 0 with a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 195302.2605459
Deduct 0 from 230 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final result is 195302.2605459 with a remainder of 2.3e-07.
