Let's divide 3691406 by 390
Let's see how many times 390 fits into 3691406.

Advancing to step 1:
When dividing 3 by 390, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 390

Let's proceed to step 2:
If we divide 36 by 390, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 390

Let's proceed to step 3:
390 can be fit into 369 0 times, resulting in a remainder of 369.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 369, we end up with 369.
Append the next digit (1) from the dividend to 369 and continue with: 3691 / 390

On to step 4:
390 goes into 3691 9 times with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 3510 away from 3691, we end up with 181.
Append the next digit (4) from the dividend to 181 and continue with: 1814 / 390

Advancing to step 5:
When dividing 1814 by 390, we get 4 with a remainder of 254.
Write down 4 as next digit of the result. 
Result so far: 94.0
Deduct 1560 from 1814 and we're left with 254.
Grab the next digit (0) from the dividend, add it to 254, then carry on: 2540 / 390

Going ahead to step 6:
When dividing 2540 by 390, we get 6 with a remainder of 200.
Write down 6 as next digit of the result. 
Result so far: 946.0
If we take 2340 away from 2540, we end up with 200.
Include the next digit (6) from the dividend after 200, then repeat: 2006 / 390

On to step 7:
2006 divided by 390 is 5 with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 9465.0
If we take 1950 away from 2006, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
When dividing 560 by 390, we get 1 with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 9465.1
If we subtract 390 from 560, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 9:
If we divide 1700 by 390, we get 4 and a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 9465.14
Deduct 1560 from 1700 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
390 goes into 1400 3 times with a remainder of 230.
Use 3 as the next digit of our solution. 
Result so far: 9465.143
If we take 1170 away from 1400, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
2300 divided by 390 is 5 with a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 9465.1435
Deduct 1950 from 2300 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 12:
390 can be fit into 3500 8 times, resulting in a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 9465.14358
Deduct 3120 from 3500 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 13:
3800 divided by 390 is 9 with a remainder of 290.
Put 9 as the next digit of the answer. 
Result so far: 9465.143589
Subtracting 3510 from 3800 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 14:
If we divide 2900 by 390, we get 7 and a remainder of 170.
The next digit of our result is 7. 
Result so far: 9465.1435897
If we take 2730 away from 2900, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 15:
The number 390 fits into 1700 4 times, leaving a remainder of 140.
Put 4 as the next digit of the answer. 
Result so far: 9465.14358974
Deduct 1560 from 1700 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

After the division, we end up with 9465.14358974 and a remainder of 1.4e-07.
