370090 ÷ 39 
Let's see how many times 39 fits into 370090.

Step 1:
When dividing 3 by 39, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 39

Going ahead to step 2:
When dividing 37 by 39, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Take the next digit (0) from the dividend and append it to 37, then repeat: 370 / 39

Advancing to step 3:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 351 away from 370, we end up with 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 39

Step 4:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 94.0
The remainder is 34 after subtracting 156 from 190.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 39

Moving on to step 5:
39 can be fit into 349 8 times, resulting in a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 948.0
The remainder is 37 after subtracting 312 from 349.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 39

Let's proceed to step 6:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9489.0
Subtracting 351 from 370 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 9489.4
Deduct 156 from 190 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
The number 39 fits into 340 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 9489.48
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 39, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 9489.487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
39 can be fit into 70 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 9489.4871
If we subtract 39 from 70, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 11:
310 divided by 39 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 9489.48717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 9489.487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
When dividing 190 by 39, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 9489.4871794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 9489.48717948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 9489.48717948, with a leftover of 2.8e-08.
