Let's divide 77645999 by 457
We want to divide 77645999 by 457.

Advancing to step 1:
457 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
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 457

Going ahead to step 2:
If we divide 77 by 457, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 457

Let's proceed to step 3:
The number 457 fits into 776 1 times, leaving a remainder of 319.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 457 away from 776, we end up with 319.
Fetch the next digit (4) from the dividend, attach it to 319 and continue: 3194 / 457

Moving on to step 4:
The number 457 fits into 3194 6 times, leaving a remainder of 452.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 2742 from 3194 leaves us with 452.
Bring next digit (5) of the dividend behind the 452 and repeat the process: 4525 / 457

Step 5:
457 goes into 4525 9 times with a remainder of 412.
Write down 9 as next digit of the result. 
Result so far: 169.0
If we subtract 4113 from 4525, we get 412.
Append the next digit (9) from the dividend to 412 and continue with: 4129 / 457

Going ahead to step 6:
4129 divided by 457 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 1699.0
Subtracting 4113 from 4129 leaves us with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 457

Let's proceed to step 7:
When dividing 169 by 457, we get 0 with a remainder of 169.
Put 0 as the next digit of the answer. 
Result so far: 16990.0
Subtract 0 from 169 to get 169.
Grab the next digit (9) from the dividend, add it to 169, then carry on: 1699 / 457

On to step 8:
The number 457 fits into 1699 3 times, leaving a remainder of 328.
Record the quotient 3 as the next digit in the result. 
Result so far: 169903.0
Subtract 1371 from 1699 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 9:
457 can be fit into 3280 7 times, resulting in a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 169903.7
Subtracting 3199 from 3280 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
457 can be fit into 810 1 times, resulting in a remainder of 353.
Use 1 as the next digit of our solution. 
Result so far: 169903.71
Deduct 457 from 810 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 11:
If we divide 3530 by 457, we get 7 and a remainder of 331.
Put 7 as the next digit of the answer. 
Result so far: 169903.717
Subtract 3199 from 3530 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 12:
3310 divided by 457 is 7 with a remainder of 111.
The number 7 becomes the next digit in our result. 
Result so far: 169903.7177
If we take 3199 away from 3310, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

After the division, we end up with 169903.7177 and a remainder of 0.00111.
