We look at the division of 85400558 by 103 
Let's see how many times 103 fits into 85400558.

On to step 1:
When dividing 8 by 103, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 103

Advancing to step 2:
The number 103 fits into 85 0 times, leaving a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 103

Step 3:
If we divide 854 by 103, we get 8 and a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 30 after subtracting 824 from 854.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 103

On to step 4:
When dividing 300 by 103, we get 2 with a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtracting 206 from 300 leaves us with 94.
Bring next digit (0) of the dividend behind the 94 and repeat the process: 940 / 103

Let's proceed to step 5:
The number 103 fits into 940 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 829.0
The remainder is 13 after subtracting 927 from 940.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 103

Advancing to step 6:
103 can be fit into 135 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 8291.0
If we take 103 away from 135, we end up with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 103

Advancing to step 7:
103 can be fit into 325 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 82913.0
Subtracting 309 from 325 leaves us with 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 103

Step 8:
103 goes into 168 1 times with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 829131.0
The remainder is 65 after subtracting 103 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
650 divided by 103 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 829131.6
If we subtract 618 from 650, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
103 goes into 320 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 829131.63
Deduct 309 from 320 and we're left with 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 11:
110 divided by 103 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 829131.631
Subtract 103 from 110 to 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 12:
When dividing 70 by 103, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 829131.631
Subtract 0 from 70 to 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 13:
700 divided by 103 is 6 with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 829131.63106
Subtracting 618 from 700 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 14:
103 goes into 820 7 times with a remainder of 99.
The next digit of our result is 7. 
Result so far: 829131.631067
Subtract 721 from 820 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 15:
103 can be fit into 990 9 times, resulting in a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 829131.6310679
The remainder is 63 after subtracting 927 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 16:
If we divide 630 by 103, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 829131.63106796
The remainder is 12 after subtracting 618 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 829131.63106796, and the remainder is 1.2e-08.
