7428254 ÷ 816 
We want to figure out the number of times 7428254 can be divided by 816.

Let's proceed to step 1:
7 divided by 816 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 816

Advancing to step 2:
When dividing 74 by 816, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Grab the next digit (2) from the dividend, add it to 74, then carry on: 742 / 816

Going ahead to step 3:
The number 816 fits into 742 0 times, leaving a remainder of 742.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 742 and we're left with 742.
Fetch the next digit (8) from the dividend, attach it to 742 and continue: 7428 / 816

Step 4:
The number 816 fits into 7428 9 times, leaving a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 84 after subtracting 7344 from 7428.
Bring next digit (2) of the dividend behind the 84 and repeat the process: 842 / 816

Going ahead to step 5:
842 divided by 816 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 91.0
Subtracting 816 from 842 leaves us with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 816

Going ahead to step 6:
When dividing 265 by 816, we get 0 with a remainder of 265.
Record the quotient 0 as the next digit in the result. 
Result so far: 910.0
Subtract 0 from 265 to get 265.
Bring next digit (4) of the dividend behind the 265 and repeat the process: 2654 / 816

Moving on to step 7:
816 goes into 2654 3 times with a remainder of 206.
The number 3 becomes the next digit in our result. 
Result so far: 9103.0
If we take 2448 away from 2654, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 8:
2060 divided by 816 is 2 with a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 9103.2
Subtracting 1632 from 2060 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 9:
816 goes into 4280 5 times with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 9103.25
Deduct 4080 from 4280 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
816 goes into 2000 2 times with a remainder of 368.
Record the quotient 2 as the next digit in the result. 
Result so far: 9103.252
Subtracting 1632 from 2000 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
816 can be fit into 3680 4 times, resulting in a remainder of 416.
Put 4 as the next digit of the answer. 
Result so far: 9103.2524
If we subtract 3264 from 3680, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 12:
816 can be fit into 4160 5 times, resulting in a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 9103.25245
If we subtract 4080 from 4160, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
816 can be fit into 800 0 times, resulting in a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 9103.25245
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 14:
816 can be fit into 8000 9 times, resulting in a remainder of 656.
Use 9 as the next digit of our solution. 
Result so far: 9103.2524509
If we subtract 7344 from 8000, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 15:
If we divide 6560 by 816, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 9103.25245098
Subtracting 6528 from 6560 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 9103.25245098, with a leftover of 3.2e-08.
