Let's divide 39361888 by 310
We're looking to find how many times 310 goes into 39361888.

On to step 1:
If we divide 3 by 310, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 310

Going ahead to step 2:
310 can be fit into 39 0 times, resulting in a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 310

Moving on to step 3:
If we divide 393 by 310, we get 1 and a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 310 away from 393, we end up with 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 310

Advancing to step 4:
If we divide 836 by 310, we get 2 and a remainder of 216.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 620 from 836 and we're left with 216.
Bring next digit (1) of the dividend behind the 216 and repeat the process: 2161 / 310

Advancing to step 5:
310 goes into 2161 6 times with a remainder of 301.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtracting 1860 from 2161 leaves us with 301.
Grab the next digit (8) from the dividend, add it to 301, then carry on: 3018 / 310

On to step 6:
310 can be fit into 3018 9 times, resulting in a remainder of 228.
The number 9 becomes the next digit in our result. 
Result so far: 1269.0
Deduct 2790 from 3018 and we're left with 228.
Include the next digit (8) from the dividend after 228, then repeat: 2288 / 310

Advancing to step 7:
When dividing 2288 by 310, we get 7 with a remainder of 118.
The next digit of our result is 7. 
Result so far: 12697.0
If we subtract 2170 from 2288, we get 118.
Append the next digit (8) from the dividend to 118 and continue with: 1188 / 310

Step 8:
310 can be fit into 1188 3 times, resulting in a remainder of 258.
Put 3 as the next digit of the answer. 
Result so far: 126973.0
Subtract 930 from 1188 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 9:
310 goes into 2580 8 times with a remainder of 100.
The next digit of our result is 8. 
Result so far: 126973.8
If we take 2480 away from 2580, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
The number 310 fits into 1000 3 times, leaving a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 126973.83
Deduct 930 from 1000 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
The number 310 fits into 700 2 times, leaving a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 126973.832
If we subtract 620 from 700, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
When dividing 800 by 310, we get 2 with a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 126973.8322
Subtract 620 from 800 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 126973.8322, with a leftover of 0.0018.
