42839664 ÷ 939 
We want to divide 42839664 by 939.

Going ahead to step 1:
939 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 939

Advancing to step 2:
The number 939 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 939

Let's proceed to step 3:
When dividing 428 by 939, we get 0 with a remainder of 428.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 428 and we're left with 428.
Fetch the next digit (3) from the dividend, attach it to 428 and continue: 4283 / 939

Let's proceed to step 4:
939 can be fit into 4283 4 times, resulting in a remainder of 527.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 3756 from 4283 and we're left with 527.
Fetch the next digit (9) from the dividend, attach it to 527 and continue: 5279 / 939

Moving on to step 5:
The number 939 fits into 5279 5 times, leaving a remainder of 584.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 4695 from 5279 and we're left with 584.
Fetch the next digit (6) from the dividend, attach it to 584 and continue: 5846 / 939

Let's proceed to step 6:
If we divide 5846 by 939, we get 6 and a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 456.0
If we take 5634 away from 5846, we end up with 212.
Include the next digit (6) from the dividend after 212, then repeat: 2126 / 939

Moving on to step 7:
2126 divided by 939 is 2 with a remainder of 248.
The next digit of our result is 2. 
Result so far: 4562.0
Subtract 1878 from 2126 to get 248.
Take the next digit (4) from the dividend and append it to 248, then repeat: 2484 / 939

Going ahead to step 8:
The number 939 fits into 2484 2 times, leaving a remainder of 606.
Use 2 as the next digit of our solution. 
Result so far: 45622.0
If we subtract 1878 from 2484, we get 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

On to step 9:
The number 939 fits into 6060 6 times, leaving a remainder of 426.
Use 6 as the next digit of our solution. 
Result so far: 45622.6
Deduct 5634 from 6060 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 10:
The number 939 fits into 4260 4 times, leaving a remainder of 504.
The next digit of our result is 4. 
Result so far: 45622.64
Deduct 3756 from 4260 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 11:
When dividing 5040 by 939, we get 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 45622.645
If we take 4695 away from 5040, we end up with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 12:
When dividing 3450 by 939, we get 3 with a remainder of 633.
The next digit of our result is 3. 
Result so far: 45622.6453
If we take 2817 away from 3450, we end up with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 13:
The number 939 fits into 6330 6 times, leaving a remainder of 696.
The next digit of our result is 6. 
Result so far: 45622.64536
If we subtract 5634 from 6330, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Step 14:
The number 939 fits into 6960 7 times, leaving a remainder of 387.
Use 7 as the next digit of our solution. 
Result so far: 45622.645367
If we take 6573 away from 6960, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 15:
3870 divided by 939 is 4 with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 45622.6453674
The remainder is 114 after subtracting 3756 from 3870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 16:
1140 divided by 939 is 1 with a remainder of 201.
Record the quotient 1 as the next digit in the result. 
Result so far: 45622.64536741
If we take 939 away from 1140, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

In conclusion, the division gives 45622.64536741 with a balance of 2.01e-07.
