We look at the division of 619603 by 90 
We want to figure out the number of times 619603 can be divided by 90.

Advancing to step 1:
90 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 90

On to step 2:
If we divide 61 by 90, we get 0 and a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (9) from the dividend, attach it to 61 and continue: 619 / 90

Going ahead to step 3:
90 goes into 619 6 times with a remainder of 79.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 540 from 619 and we're left with 79.
Take the next digit (6) from the dividend and append it to 79, then repeat: 796 / 90

Advancing to step 4:
The number 90 fits into 796 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtracting 720 from 796 leaves us with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 90

On to step 5:
The number 90 fits into 760 8 times, leaving a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 688.0
The remainder is 40 after subtracting 720 from 760.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 90

Let's proceed to step 6:
403 divided by 90 is 4 with a remainder of 43.
The number 4 becomes the next digit in our result. 
Result so far: 6884.0
Subtracting 360 from 403 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
430 divided by 90 is 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 6884.4
Subtract 360 from 430 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 8:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 6884.47
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
When dividing 700 by 90, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 6884.477
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 6884.477 with a remaining 0.007.
