We look at the division of 53578579 by 747 
We're looking to find how many times 747 goes into 53578579.

Advancing to step 1:
747 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 747

Moving on to step 2:
If we divide 53 by 747, we get 0 and a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 747

Going ahead to step 3:
747 goes into 535 0 times with a remainder of 535.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 535 and we're left with 535.
Include the next digit (7) from the dividend after 535, then repeat: 5357 / 747

Advancing to step 4:
The number 747 fits into 5357 7 times, leaving a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 128 after subtracting 5229 from 5357.
Bring next digit (8) of the dividend behind the 128 and repeat the process: 1288 / 747

Advancing to step 5:
747 can be fit into 1288 1 times, resulting in a remainder of 541.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Subtracting 747 from 1288 leaves us with 541.
Take the next digit (5) from the dividend and append it to 541, then repeat: 5415 / 747

Step 6:
If we divide 5415 by 747, we get 7 and a remainder of 186.
The next digit of our result is 7. 
Result so far: 717.0
The remainder is 186 after subtracting 5229 from 5415.
Take the next digit (7) from the dividend and append it to 186, then repeat: 1867 / 747

Let's proceed to step 7:
The number 747 fits into 1867 2 times, leaving a remainder of 373.
Use 2 as the next digit of our solution. 
Result so far: 7172.0
If we take 1494 away from 1867, we end up with 373.
Grab the next digit (9) from the dividend, add it to 373, then carry on: 3739 / 747

Let's proceed to step 8:
747 can be fit into 3739 5 times, resulting in a remainder of 4.
The next digit of our result is 5. 
Result so far: 71725.0
The remainder is 4 after subtracting 3735 from 3739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 747, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 71725.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 747 fits into 400 0 times, leaving a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 71725.0
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 71725.0, with a leftover of 0.4.
