We look at the division of 7958630 by 406 
Our goal is to divide 7958630 by 406.

Step 1:
When dividing 7 by 406, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 406

Advancing to step 2:
The number 406 fits into 79 0 times, leaving a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Bring next digit (5) of the dividend behind the 79 and repeat the process: 795 / 406

Step 3:
If we divide 795 by 406, we get 1 and a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 406 from 795 leaves us with 389.
Fetch the next digit (8) from the dividend, attach it to 389 and continue: 3898 / 406

Step 4:
When dividing 3898 by 406, we get 9 with a remainder of 244.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 3654 from 3898 and we're left with 244.
Bring next digit (6) of the dividend behind the 244 and repeat the process: 2446 / 406

On to step 5:
When dividing 2446 by 406, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Subtract 2436 from 2446 to get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 406

Advancing to step 6:
The number 406 fits into 103 0 times, leaving a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 1960.0
Subtracting 0 from 103 leaves us with 103.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 406

Moving on to step 7:
If we divide 1030 by 406, we get 2 and a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 19602.0
If we subtract 812 from 1030, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 8:
If we divide 2180 by 406, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 19602.5
If we take 2030 away from 2180, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 9:
1500 divided by 406 is 3 with a remainder of 282.
Record the quotient 3 as the next digit in the result. 
Result so far: 19602.53
Subtract 1218 from 1500 to get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 10:
The number 406 fits into 2820 6 times, leaving a remainder of 384.
The next digit of our result is 6. 
Result so far: 19602.536
Subtracting 2436 from 2820 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 11:
406 can be fit into 3840 9 times, resulting in a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 19602.5369
Deduct 3654 from 3840 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 12:
If we divide 1860 by 406, we get 4 and a remainder of 236.
Use 4 as the next digit of our solution. 
Result so far: 19602.53694
Subtracting 1624 from 1860 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.

Step 13:
406 goes into 2360 5 times with a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 19602.536945
Subtract 2030 from 2360 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
406 goes into 3300 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 19602.5369458
If we subtract 3248 from 3300, 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 15:
406 goes into 520 1 times with a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 19602.53694581
Subtract 406 from 520 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 19602.53694581 and a remainder of 1.14e-07.
