77487942 ÷ 437 
We want to divide 77487942 by 437.

Moving on to step 1:
If we divide 7 by 437, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 437

Advancing to step 2:
437 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 437

On to step 3:
When dividing 774 by 437, we get 1 with a remainder of 337.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 437 from 774, we get 337.
Append the next digit (8) from the dividend to 337 and continue with: 3378 / 437

Moving on to step 4:
437 goes into 3378 7 times with a remainder of 319.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 3059 from 3378 leaves us with 319.
Grab the next digit (7) from the dividend, add it to 319, then carry on: 3197 / 437

Let's proceed to step 5:
If we divide 3197 by 437, we get 7 and a remainder of 138.
The next digit of our result is 7. 
Result so far: 177.0
If we take 3059 away from 3197, we end up with 138.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 437

Advancing to step 6:
When dividing 1389 by 437, we get 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 1773.0
Subtracting 1311 from 1389 leaves us with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 437

Moving on to step 7:
784 divided by 437 is 1 with a remainder of 347.
The next digit of our result is 1. 
Result so far: 17731.0
Subtracting 437 from 784 leaves us with 347.
Take the next digit (2) from the dividend and append it to 347, then repeat: 3472 / 437

Advancing to step 8:
When dividing 3472 by 437, we get 7 with a remainder of 413.
Use 7 as the next digit of our solution. 
Result so far: 177317.0
Subtract 3059 from 3472 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 9:
437 goes into 4130 9 times with a remainder of 197.
Record the quotient 9 as the next digit in the result. 
Result so far: 177317.9
If we take 3933 away from 4130, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 10:
The number 437 fits into 1970 4 times, leaving a remainder of 222.
Record the quotient 4 as the next digit in the result. 
Result so far: 177317.94
The remainder is 222 after subtracting 1748 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 11:
437 goes into 2220 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 177317.945
The remainder is 35 after subtracting 2185 from 2220.
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 12:
437 can be fit into 350 0 times, resulting in a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 177317.945
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.

Step 13:
When dividing 3500 by 437, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 177317.94508
Deduct 3496 from 3500 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 437, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 177317.94508
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 15:
437 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 177317.94508
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.

After the division, we end up with 177317.94508 and a remainder of 4e-06.
