65982161 ÷ 437 
Our goal is to divide 65982161 by 437.

Step 1:
437 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 437

Going ahead to step 2:
When dividing 65 by 437, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 437

Let's proceed to step 3:
If we divide 659 by 437, we get 1 and a remainder of 222.
The next digit of our result is 1. 
Result so far: 1.0
If we take 437 away from 659, we end up with 222.
Append the next digit (8) from the dividend to 222 and continue with: 2228 / 437

On to step 4:
The number 437 fits into 2228 5 times, leaving a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2185 from 2228 to get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 437

On to step 5:
The number 437 fits into 432 0 times, leaving a remainder of 432.
The next digit of our result is 0. 
Result so far: 150.0
The remainder is 432 after subtracting 0 from 432.
Take the next digit (1) from the dividend and append it to 432, then repeat: 4321 / 437

Step 6:
If we divide 4321 by 437, we get 9 and a remainder of 388.
The next digit of our result is 9. 
Result so far: 1509.0
Deduct 3933 from 4321 and we're left with 388.
Take the next digit (6) from the dividend and append it to 388, then repeat: 3886 / 437

Step 7:
When dividing 3886 by 437, we get 8 with a remainder of 390.
Use 8 as the next digit of our solution. 
Result so far: 15098.0
If we subtract 3496 from 3886, we get 390.
Take the next digit (1) from the dividend and append it to 390, then repeat: 3901 / 437

Step 8:
437 goes into 3901 8 times with a remainder of 405.
Record the quotient 8 as the next digit in the result. 
Result so far: 150988.0
If we take 3496 away from 3901, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 9:
437 goes into 4050 9 times with a remainder of 117.
The number 9 becomes the next digit in our result. 
Result so far: 150988.9
Subtract 3933 from 4050 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 10:
When dividing 1170 by 437, we get 2 with a remainder of 296.
The number 2 becomes the next digit in our result. 
Result so far: 150988.92
Subtracting 874 from 1170 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 11:
If we divide 2960 by 437, we get 6 and a remainder of 338.
Use 6 as the next digit of our solution. 
Result so far: 150988.926
Deduct 2622 from 2960 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 12:
The number 437 fits into 3380 7 times, leaving a remainder of 321.
The next digit of our result is 7. 
Result so far: 150988.9267
Subtract 3059 from 3380 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 13:
3210 divided by 437 is 7 with a remainder of 151.
Record the quotient 7 as the next digit in the result. 
Result so far: 150988.92677
Deduct 3059 from 3210 and we're left with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 150988.92677, with a leftover of 0.000151.
