We divide 337903 by 86
We want to figure out the number of times 337903 can be divided by 86.

On to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 86

On to step 2:
33 divided by 86 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 86

Step 3:
86 goes into 337 3 times with a remainder of 79.
The next digit of our result is 3. 
Result so far: 3.0
If we take 258 away from 337, we end up with 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 86

Step 4:
86 goes into 799 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we subtract 774 from 799, we get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 86

On to step 5:
If we divide 250 by 86, we get 2 and a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 392.0
Subtract 172 from 250 to get 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 86

Advancing to step 6:
The number 86 fits into 783 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 3929.0
If we take 774 away from 783, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 86, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 3929.1
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 86, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3929.1
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
86 goes into 400 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 3929.104
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
When dividing 560 by 86, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 3929.1046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 3929.10465
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
When dividing 100 by 86, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3929.104651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 3929.1046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 3929.1046511 and a remainder of 5.4e-07.
