We look at the division of 83438378 by 997 
We want to divide 83438378 by 997.

Going ahead to step 1:
997 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 997

On to step 2:
997 can be fit into 83 0 times, resulting in a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 997

Let's proceed to step 3:
834 divided by 997 is 0 with a remainder of 834.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 834 after subtracting 0 from 834.
Take the next digit (3) from the dividend and append it to 834, then repeat: 8343 / 997

Moving on to step 4:
8343 divided by 997 is 8 with a remainder of 367.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7976 from 8343, we get 367.
Include the next digit (8) from the dividend after 367, then repeat: 3678 / 997

Step 5:
997 goes into 3678 3 times with a remainder of 687.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 2991 from 3678 leaves us with 687.
Bring next digit (3) of the dividend behind the 687 and repeat the process: 6873 / 997

Step 6:
997 goes into 6873 6 times with a remainder of 891.
Use 6 as the next digit of our solution. 
Result so far: 836.0
Subtract 5982 from 6873 to get 891.
Bring next digit (7) of the dividend behind the 891 and repeat the process: 8917 / 997

Going ahead to step 7:
The number 997 fits into 8917 8 times, leaving a remainder of 941.
The next digit of our result is 8. 
Result so far: 8368.0
The remainder is 941 after subtracting 7976 from 8917.
Grab the next digit (8) from the dividend, add it to 941, then carry on: 9418 / 997

Step 8:
9418 divided by 997 is 9 with a remainder of 445.
Use 9 as the next digit of our solution. 
Result so far: 83689.0
Deduct 8973 from 9418 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Going ahead to step 9:
If we divide 4450 by 997, we get 4 and a remainder of 462.
The number 4 becomes the next digit in our result. 
Result so far: 83689.4
Subtract 3988 from 4450 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 10:
4620 divided by 997 is 4 with a remainder of 632.
Put 4 as the next digit of the answer. 
Result so far: 83689.44
Subtracting 3988 from 4620 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

The quotient of the division is 83689.44, and the remainder is 0.632.
