We're dividing 78254583 by 691 
We want to figure out the number of times 78254583 can be divided by 691.

Advancing to step 1:
7 divided by 691 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 691

Moving on to step 2:
78 divided by 691 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 691

Advancing to step 3:
If we divide 782 by 691, we get 1 and a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 691 away from 782, we end up with 91.
Take the next digit (5) from the dividend and append it to 91, then repeat: 915 / 691

Advancing to step 4:
691 can be fit into 915 1 times, resulting in a remainder of 224.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 691 from 915, we get 224.
Grab the next digit (4) from the dividend, add it to 224, then carry on: 2244 / 691

Going ahead to step 5:
When dividing 2244 by 691, we get 3 with a remainder of 171.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 2073 from 2244 and we're left with 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 691

Going ahead to step 6:
If we divide 1715 by 691, we get 2 and a remainder of 333.
Put 2 as the next digit of the answer. 
Result so far: 1132.0
If we take 1382 away from 1715, we end up with 333.
Bring next digit (8) of the dividend behind the 333 and repeat the process: 3338 / 691

Moving on to step 7:
3338 divided by 691 is 4 with a remainder of 574.
Write down 4 as next digit of the result. 
Result so far: 11324.0
If we subtract 2764 from 3338, we get 574.
Append the next digit (3) from the dividend to 574 and continue with: 5743 / 691

Let's proceed to step 8:
When dividing 5743 by 691, we get 8 with a remainder of 215.
Write down 8 as next digit of the result. 
Result so far: 113248.0
Subtracting 5528 from 5743 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 9:
691 goes into 2150 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 113248.3
Subtract 2073 from 2150 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
691 goes into 770 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 113248.31
The remainder is 79 after subtracting 691 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 11:
When dividing 790 by 691, we get 1 with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 113248.311
Deduct 691 from 790 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

After the division, we end up with 113248.311 and a remainder of 0.0099.
