Let's divide 39291533 by 286
We want to figure out the number of times 39291533 can be divided by 286.

Step 1:
If we divide 3 by 286, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 286

Step 2:
The number 286 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 286

On to step 3:
286 goes into 392 1 times with a remainder of 106.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 286 away from 392, we end up with 106.
Append the next digit (9) from the dividend to 106 and continue with: 1069 / 286

Moving on to step 4:
If we divide 1069 by 286, we get 3 and a remainder of 211.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 858 from 1069 leaves us with 211.
Bring next digit (1) of the dividend behind the 211 and repeat the process: 2111 / 286

Going ahead to step 5:
2111 divided by 286 is 7 with a remainder of 109.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we take 2002 away from 2111, we end up with 109.
Append the next digit (5) from the dividend to 109 and continue with: 1095 / 286

Going ahead to step 6:
If we divide 1095 by 286, we get 3 and a remainder of 237.
The number 3 becomes the next digit in our result. 
Result so far: 1373.0
The remainder is 237 after subtracting 858 from 1095.
Append the next digit (3) from the dividend to 237 and continue with: 2373 / 286

On to step 7:
If we divide 2373 by 286, we get 8 and a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 13738.0
If we take 2288 away from 2373, we end up with 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 286

On to step 8:
The number 286 fits into 853 2 times, leaving a remainder of 281.
Use 2 as the next digit of our solution. 
Result so far: 137382.0
If we take 572 away from 853, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 9:
286 can be fit into 2810 9 times, resulting in a remainder of 236.
The next digit of our result is 9. 
Result so far: 137382.9
Deduct 2574 from 2810 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 10:
286 can be fit into 2360 8 times, resulting in a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 137382.98
The remainder is 72 after subtracting 2288 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
286 goes into 720 2 times with a remainder of 148.
Write down 2 as next digit of the result. 
Result so far: 137382.982
Deduct 572 from 720 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 12:
The number 286 fits into 1480 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 137382.9825
Subtract 1430 from 1480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
500 divided by 286 is 1 with a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 137382.98251
If we subtract 286 from 500, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 14:
286 can be fit into 2140 7 times, resulting in a remainder of 138.
Put 7 as the next digit of the answer. 
Result so far: 137382.982517
If we take 2002 away from 2140, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 15:
When dividing 1380 by 286, we get 4 with a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 137382.9825174
Subtracting 1144 from 1380 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 16:
2360 divided by 286 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 137382.98251748
If we take 2288 away from 2360, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 137382.98251748 with a remaining 7.2e-08.
