Let's divide 77446586 by 455
Our goal is to divide 77446586 by 455.

On to step 1:
When dividing 7 by 455, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 455

On to step 2:
If we divide 77 by 455, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 455

On to step 3:
When dividing 774 by 455, we get 1 with a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 319 after subtracting 455 from 774.
Append the next digit (4) from the dividend to 319 and continue with: 3194 / 455

Going ahead to step 4:
If we divide 3194 by 455, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 9 after subtracting 3185 from 3194.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 455

Advancing to step 5:
96 divided by 455 is 0 with a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 96 leaves us with 96.
Fetch the next digit (5) from the dividend, attach it to 96 and continue: 965 / 455

Advancing to step 6:
The number 455 fits into 965 2 times, leaving a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 1702.0
If we take 910 away from 965, we end up with 55.
Grab the next digit (8) from the dividend, add it to 55, then carry on: 558 / 455

Step 7:
558 divided by 455 is 1 with a remainder of 103.
Put 1 as the next digit of the answer. 
Result so far: 17021.0
Subtract 455 from 558 to get 103.
Take the next digit (6) from the dividend and append it to 103, then repeat: 1036 / 455

Step 8:
When dividing 1036 by 455, we get 2 with a remainder of 126.
Use 2 as the next digit of our solution. 
Result so far: 170212.0
Subtract 910 from 1036 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
If we divide 1260 by 455, we get 2 and a remainder of 350.
Record the quotient 2 as the next digit in the result. 
Result so far: 170212.2
If we take 910 away from 1260, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
If we divide 3500 by 455, we get 7 and a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 170212.27
If we subtract 3185 from 3500, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 11:
455 goes into 3150 6 times with a remainder of 420.
Use 6 as the next digit of our solution. 
Result so far: 170212.276
If we take 2730 away from 3150, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
4200 divided by 455 is 9 with a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 170212.2769
Deduct 4095 from 4200 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 13:
If we divide 1050 by 455, we get 2 and a remainder of 140.
The next digit of our result is 2. 
Result so far: 170212.27692
If we take 910 away from 1050, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
When dividing 1400 by 455, we get 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 170212.276923
If we take 1365 away from 1400, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
If we divide 350 by 455, we get 0 and a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 170212.276923
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 16:
If we divide 3500 by 455, we get 7 and a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 170212.27692307
Subtract 3185 from 3500 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The quotient of the division is 170212.27692307, and the remainder is 3.15e-07.
