We look at the division of 7389881 by 817 
Our goal is to divide 7389881 by 817.

Step 1:
The number 817 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 817

Moving on to step 2:
817 can be fit into 73 0 times, resulting in a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 817

Let's proceed to step 3:
The number 817 fits into 738 0 times, leaving a remainder of 738.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 738 leaves us with 738.
Bring next digit (9) of the dividend behind the 738 and repeat the process: 7389 / 817

Going ahead to step 4:
If we divide 7389 by 817, we get 9 and a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7353 from 7389 to get 36.
Fetch the next digit (8) from the dividend, attach it to 36 and continue: 368 / 817

Advancing to step 5:
When dividing 368 by 817, we get 0 with a remainder of 368.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtracting 0 from 368 leaves us with 368.
Bring next digit (8) of the dividend behind the 368 and repeat the process: 3688 / 817

Moving on to step 6:
817 can be fit into 3688 4 times, resulting in a remainder of 420.
Put 4 as the next digit of the answer. 
Result so far: 904.0
The remainder is 420 after subtracting 3268 from 3688.
Append the next digit (1) from the dividend to 420 and continue with: 4201 / 817

On to step 7:
If we divide 4201 by 817, we get 5 and a remainder of 116.
The number 5 becomes the next digit in our result. 
Result so far: 9045.0
If we subtract 4085 from 4201, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 8:
1160 divided by 817 is 1 with a remainder of 343.
Record the quotient 1 as the next digit in the result. 
Result so far: 9045.1
Subtracting 817 from 1160 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 9:
If we divide 3430 by 817, we get 4 and a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 9045.14
The remainder is 162 after subtracting 3268 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 10:
1620 divided by 817 is 1 with a remainder of 803.
The number 1 becomes the next digit in our result. 
Result so far: 9045.141
If we subtract 817 from 1620, we get 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8030, and continue the process.

On to step 11:
817 can be fit into 8030 9 times, resulting in a remainder of 677.
The number 9 becomes the next digit in our result. 
Result so far: 9045.1419
Deduct 7353 from 8030 and we're left with 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Step 12:
817 can be fit into 6770 8 times, resulting in a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 9045.14198
Deduct 6536 from 6770 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 13:
When dividing 2340 by 817, we get 2 with a remainder of 706.
The number 2 becomes the next digit in our result. 
Result so far: 9045.141982
Subtract 1634 from 2340 to get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Going ahead to step 14:
817 can be fit into 7060 8 times, resulting in a remainder of 524.
The next digit of our result is 8. 
Result so far: 9045.1419828
Subtract 6536 from 7060 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

On to step 15:
817 goes into 5240 6 times with a remainder of 338.
The number 6 becomes the next digit in our result. 
Result so far: 9045.14198286
If we take 4902 away from 5240, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

After the division, we end up with 9045.14198286 and a remainder of 3.38e-07.
