We're dividing 435991 by 57 
We want to divide 435991 by 57.

Moving on to step 1:
When dividing 4 by 57, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 57

Going ahead to step 2:
When dividing 43 by 57, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 57

Moving on to step 3:
57 can be fit into 435 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 399 away from 435, we end up with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 57

Advancing to step 4:
57 goes into 369 6 times with a remainder of 27.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 342 from 369 to get 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 57

Advancing to step 5:
57 can be fit into 279 4 times, resulting in a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 764.0
Subtract 228 from 279 to get 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 57

Going ahead to step 6:
When dividing 511 by 57, we get 8 with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 7648.0
If we subtract 456 from 511, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
If we divide 550 by 57, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 7648.9
The remainder is 37 after subtracting 513 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
If we divide 370 by 57, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 7648.96
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 57 fits into 280 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 7648.964
Subtracting 228 from 280 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
When dividing 520 by 57, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 7648.9649
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
57 goes into 70 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 7648.96491
If we subtract 57 from 70, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
57 can be fit into 130 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 7648.964912
Subtract 114 from 130 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 57, we get 2 and a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 7648.9649122
The remainder is 46 after subtracting 114 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 7648.9649122 with a balance of 4.6e-07.
