We look at the division of 77851224 by 203 
We want to figure out the number of times 77851224 can be divided by 203.

Moving on to step 1:
When dividing 7 by 203, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 203

Let's proceed to step 2:
203 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 203

Advancing to step 3:
The number 203 fits into 778 3 times, leaving a remainder of 169.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 609 from 778 to get 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 203

On to step 4:
203 goes into 1695 8 times with a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 1624 from 1695, we get 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 203

Step 5:
203 goes into 711 3 times with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 383.0
If we subtract 609 from 711, we get 102.
Bring next digit (2) of the dividend behind the 102 and repeat the process: 1022 / 203

Advancing to step 6:
If we divide 1022 by 203, we get 5 and a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 3835.0
Subtract 1015 from 1022 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 203

On to step 7:
203 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 38350.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 203

Advancing to step 8:
203 can be fit into 724 3 times, resulting in a remainder of 115.
The next digit of our result is 3. 
Result so far: 383503.0
Subtracting 609 from 724 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 9:
The number 203 fits into 1150 5 times, leaving a remainder of 135.
The next digit of our result is 5. 
Result so far: 383503.5
Subtract 1015 from 1150 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 10:
203 goes into 1350 6 times with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 383503.56
Deduct 1218 from 1350 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 11:
The number 203 fits into 1320 6 times, leaving a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 383503.566
Subtract 1218 from 1320 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 383503.566, with a leftover of 0.0102.
