We're dividing 39123606 by 837 
We want to figure out the number of times 39123606 can be divided by 837.

Step 1:
If we divide 3 by 837, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 837

Step 2:
The number 837 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 837

On to step 3:
The number 837 fits into 391 0 times, leaving a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 391 and we're left with 391.
Append the next digit (2) from the dividend to 391 and continue with: 3912 / 837

Going ahead to step 4:
If we divide 3912 by 837, we get 4 and a remainder of 564.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3348 from 3912 and we're left with 564.
Grab the next digit (3) from the dividend, add it to 564, then carry on: 5643 / 837

Going ahead to step 5:
837 can be fit into 5643 6 times, resulting in a remainder of 621.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Deduct 5022 from 5643 and we're left with 621.
Bring next digit (6) of the dividend behind the 621 and repeat the process: 6216 / 837

Going ahead to step 6:
The number 837 fits into 6216 7 times, leaving a remainder of 357.
Record the quotient 7 as the next digit in the result. 
Result so far: 467.0
Subtracting 5859 from 6216 leaves us with 357.
Bring next digit (0) of the dividend behind the 357 and repeat the process: 3570 / 837

Let's proceed to step 7:
If we divide 3570 by 837, we get 4 and a remainder of 222.
Use 4 as the next digit of our solution. 
Result so far: 4674.0
If we subtract 3348 from 3570, we get 222.
Bring next digit (6) of the dividend behind the 222 and repeat the process: 2226 / 837

Going ahead to step 8:
2226 divided by 837 is 2 with a remainder of 552.
Put 2 as the next digit of the answer. 
Result so far: 46742.0
If we take 1674 away from 2226, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 9:
837 can be fit into 5520 6 times, resulting in a remainder of 498.
The number 6 becomes the next digit in our result. 
Result so far: 46742.6
The remainder is 498 after subtracting 5022 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Moving on to step 10:
837 can be fit into 4980 5 times, resulting in a remainder of 795.
The next digit of our result is 5. 
Result so far: 46742.65
Subtract 4185 from 4980 to get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Going ahead to step 11:
837 goes into 7950 9 times with a remainder of 417.
Write down 9 as next digit of the result. 
Result so far: 46742.659
The remainder is 417 after subtracting 7533 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Going ahead to step 12:
The number 837 fits into 4170 4 times, leaving a remainder of 822.
Use 4 as the next digit of our solution. 
Result so far: 46742.6594
Deduct 3348 from 4170 and we're left with 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Step 13:
8220 divided by 837 is 9 with a remainder of 687.
Write down 9 as next digit of the result. 
Result so far: 46742.65949
Deduct 7533 from 8220 and we're left with 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

On to step 14:
When dividing 6870 by 837, we get 8 with a remainder of 174.
The next digit of our result is 8. 
Result so far: 46742.659498
Subtract 6696 from 6870 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 15:
When dividing 1740 by 837, we get 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 46742.6594982
If we take 1674 away from 1740, we end up 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.

Going ahead to step 16:
When dividing 660 by 837, we get 0 with a remainder of 660.
Put 0 as the next digit of the answer. 
Result so far: 46742.6594982
Subtract 0 from 660 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

In conclusion, the division gives 46742.6594982 with a balance of 6.6e-07.
