We're dividing 75561025 by 455 
Our goal is to divide 75561025 by 455.

On to step 1:
455 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 455

Let's proceed to step 2:
455 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 455

On to step 3:
455 can be fit into 755 1 times, resulting in a remainder of 300.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 455 from 755 and we're left with 300.
Append the next digit (6) from the dividend to 300 and continue with: 3006 / 455

Moving on to step 4:
When dividing 3006 by 455, we get 6 with a remainder of 276.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 2730 from 3006 to get 276.
Take the next digit (1) from the dividend and append it to 276, then repeat: 2761 / 455

Step 5:
2761 divided by 455 is 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 166.0
If we take 2730 away from 2761, we end up with 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 455

Moving on to step 6:
310 divided by 455 is 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 1660.0
The remainder is 310 after subtracting 0 from 310.
Take the next digit (2) from the dividend and append it to 310, then repeat: 3102 / 455

On to step 7:
When dividing 3102 by 455, we get 6 with a remainder of 372.
Write down 6 as next digit of the result. 
Result so far: 16606.0
If we subtract 2730 from 3102, we get 372.
Take the next digit (5) from the dividend and append it to 372, then repeat: 3725 / 455

Let's proceed to step 8:
The number 455 fits into 3725 8 times, leaving a remainder of 85.
The next digit of our result is 8. 
Result so far: 166068.0
Subtract 3640 from 3725 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
The number 455 fits into 850 1 times, leaving a remainder of 395.
Write down 1 as next digit of the result. 
Result so far: 166068.1
If we take 455 away from 850, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 10:
If we divide 3950 by 455, we get 8 and a remainder of 310.
Use 8 as the next digit of our solution. 
Result so far: 166068.18
The remainder is 310 after subtracting 3640 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 11:
If we divide 3100 by 455, we get 6 and a remainder of 370.
The next digit of our result is 6. 
Result so far: 166068.186
The remainder is 370 after subtracting 2730 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 12:
When dividing 3700 by 455, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 166068.1868
If we subtract 3640 from 3700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
455 goes into 600 1 times with a remainder of 145.
The number 1 becomes the next digit in our result. 
Result so far: 166068.18681
Subtracting 455 from 600 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 14:
The number 455 fits into 1450 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 166068.186813
Subtracting 1365 from 1450 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 15:
The number 455 fits into 850 1 times, leaving a remainder of 395.
The next digit of our result is 1. 
Result so far: 166068.1868131
Subtracting 455 from 850 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Advancing to step 16:
The number 455 fits into 3950 8 times, leaving a remainder of 310.
Write down 8 as next digit of the result. 
Result so far: 166068.18681318
If we subtract 3640 from 3950, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The final outcome is 166068.18681318, with a leftover of 3.1e-07.
