We look at the division of 439937 by 91 
Our goal is to divide 439937 by 91.

Moving on to step 1:
When dividing 4 by 91, 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.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 91

On to step 2:
If we divide 43 by 91, we get 0 and 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.
Take the next digit (9) from the dividend and append it to 43, then repeat: 439 / 91

Moving on to step 3:
91 goes into 439 4 times with a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 364 from 439 leaves us with 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 91

Going ahead to step 4:
The number 91 fits into 759 8 times, leaving a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 728 from 759 and we're left with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 91

On to step 5:
If we divide 313 by 91, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 483.0
Subtracting 273 from 313 leaves us with 40.
Include the next digit (7) from the dividend after 40, then repeat: 407 / 91

On to step 6:
When dividing 407 by 91, we get 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 4834.0
Subtracting 364 from 407 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
91 can be fit into 430 4 times, resulting in a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 4834.4
Subtracting 364 from 430 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
The number 91 fits into 660 7 times, leaving a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 4834.47
Subtracting 637 from 660 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
91 goes into 230 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 4834.472
Subtracting 182 from 230 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
91 goes into 480 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4834.4725
Deduct 455 from 480 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
91 goes into 250 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 4834.47252
Subtracting 182 from 250 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
91 can be fit into 680 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 4834.472527
The remainder is 43 after subtracting 637 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
If we divide 430 by 91, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4834.4725274
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
91 goes into 660 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 4834.47252747
If we take 637 away from 660, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 4834.47252747, and the remainder is 2.3e-08.
