437648 ÷ 77 
We want to divide 437648 by 77.

Going ahead to step 1:
77 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 77

Going ahead to step 2:
When dividing 43 by 77, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 77

Step 3:
437 divided by 77 is 5 with a remainder of 52.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 385 away from 437, we end up with 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 77

On to step 4:
526 divided by 77 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 462 from 526, we get 64.
Fetch the next digit (4) from the dividend, attach it to 64 and continue: 644 / 77

Step 5:
If we divide 644 by 77, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 568.0
The remainder is 28 after subtracting 616 from 644.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 77

Let's proceed to step 6:
If we divide 288 by 77, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 5683.0
If we subtract 231 from 288, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
77 can be fit into 570 7 times, resulting in a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 5683.7
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
77 goes into 310 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 5683.74
If we take 308 away from 310, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 77 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5683.74
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
200 divided by 77 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 5683.7402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
77 goes into 460 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 5683.74025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
The number 77 fits into 750 9 times, leaving a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 5683.740259
Subtracting 693 from 750 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
If we divide 570 by 77, we get 7 and a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 5683.7402597
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 5683.74025974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 5683.74025974 with a remainder of 2e-09.
