Let's divide 15674806 by 391
We want to figure out the number of times 15674806 can be divided by 391.

Step 1:
391 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 391

Let's proceed to step 2:
The number 391 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 391

Moving on to step 3:
If we divide 156 by 391, we get 0 and a remainder of 156.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 156 to get 156.
Fetch the next digit (7) from the dividend, attach it to 156 and continue: 1567 / 391

Advancing to step 4:
The number 391 fits into 1567 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1564 away from 1567, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 391

Step 5:
The number 391 fits into 34 0 times, leaving a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 391

On to step 6:
391 goes into 348 0 times with a remainder of 348.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
Deduct 0 from 348 and we're left with 348.
Grab the next digit (0) from the dividend, add it to 348, then carry on: 3480 / 391

Let's proceed to step 7:
If we divide 3480 by 391, we get 8 and a remainder of 352.
The number 8 becomes the next digit in our result. 
Result so far: 4008.0
The remainder is 352 after subtracting 3128 from 3480.
Include the next digit (6) from the dividend after 352, then repeat: 3526 / 391

Going ahead to step 8:
3526 divided by 391 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 40089.0
If we subtract 3519 from 3526, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
When dividing 70 by 391, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 40089.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
391 goes into 700 1 times with a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 40089.01
Deduct 391 from 700 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 11:
391 goes into 3090 7 times with a remainder of 353.
Record the quotient 7 as the next digit in the result. 
Result so far: 40089.017
If we take 2737 away from 3090, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 12:
The number 391 fits into 3530 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 40089.0179
Subtract 3519 from 3530 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
If we divide 110 by 391, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 40089.0179
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 14:
1100 divided by 391 is 2 with a remainder of 318.
Record the quotient 2 as the next digit in the result. 
Result so far: 40089.017902
If we subtract 782 from 1100, we get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 15:
When dividing 3180 by 391, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 40089.0179028
If we subtract 3128 from 3180, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 16:
391 goes into 520 1 times with a remainder of 129.
Put 1 as the next digit of the answer. 
Result so far: 40089.01790281
Subtract 391 from 520 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

After the division, we end up with 40089.01790281 and a remainder of 1.29e-07.
