We look at the division of 78509375 by 574 
We want to figure out the number of times 78509375 can be divided by 574.

Going ahead to step 1:
If we divide 7 by 574, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 574

Advancing to step 2:
When dividing 78 by 574, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 574

Moving on to step 3:
If we divide 785 by 574, we get 1 and a remainder of 211.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 211 after subtracting 574 from 785.
Fetch the next digit (0) from the dividend, attach it to 211 and continue: 2110 / 574

Let's proceed to step 4:
The number 574 fits into 2110 3 times, leaving a remainder of 388.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1722 from 2110 leaves us with 388.
Fetch the next digit (9) from the dividend, attach it to 388 and continue: 3889 / 574

Step 5:
When dividing 3889 by 574, we get 6 with a remainder of 445.
The next digit of our result is 6. 
Result so far: 136.0
If we subtract 3444 from 3889, we get 445.
Take the next digit (3) from the dividend and append it to 445, then repeat: 4453 / 574

Step 6:
If we divide 4453 by 574, we get 7 and a remainder of 435.
Use 7 as the next digit of our solution. 
Result so far: 1367.0
Deduct 4018 from 4453 and we're left with 435.
Take the next digit (7) from the dividend and append it to 435, then repeat: 4357 / 574

Let's proceed to step 7:
When dividing 4357 by 574, we get 7 with a remainder of 339.
Put 7 as the next digit of the answer. 
Result so far: 13677.0
The remainder is 339 after subtracting 4018 from 4357.
Append the next digit (5) from the dividend to 339 and continue with: 3395 / 574

Advancing to step 8:
When dividing 3395 by 574, we get 5 with a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 136775.0
If we subtract 2870 from 3395, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Step 9:
When dividing 5250 by 574, we get 9 with a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 136775.9
Subtracting 5166 from 5250 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
When dividing 840 by 574, we get 1 with a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 136775.91
Subtracting 574 from 840 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 11:
574 goes into 2660 4 times with a remainder of 364.
Use 4 as the next digit of our solution. 
Result so far: 136775.914
Subtracting 2296 from 2660 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 12:
574 can be fit into 3640 6 times, resulting in a remainder of 196.
The next digit of our result is 6. 
Result so far: 136775.9146
If we take 3444 away from 3640, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 13:
The number 574 fits into 1960 3 times, leaving a remainder of 238.
Record the quotient 3 as the next digit in the result. 
Result so far: 136775.91463
If we take 1722 away from 1960, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 14:
If we divide 2380 by 574, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 136775.914634
Subtract 2296 from 2380 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 15:
574 can be fit into 840 1 times, resulting in a remainder of 266.
Use 1 as the next digit of our solution. 
Result so far: 136775.9146341
Deduct 574 from 840 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 16:
The number 574 fits into 2660 4 times, leaving a remainder of 364.
Use 4 as the next digit of our solution. 
Result so far: 136775.91463414
Subtract 2296 from 2660 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

The final result is 136775.91463414 with a remainder of 3.64e-07.
