551107 divided by 90 
Let's see how many times 90 fits into 551107.

Step 1:
5 divided by 90 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 90

Let's proceed to step 2:
The number 90 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 90

On to step 3:
If we divide 551 by 90, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 540 from 551, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 90

Step 4:
If we divide 111 by 90, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 61.0
The remainder is 21 after subtracting 90 from 111.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 90

Moving on to step 5:
90 can be fit into 210 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 612.0
Subtract 180 from 210 to get 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 90

Going ahead to step 6:
307 divided by 90 is 3 with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 6123.0
If we subtract 270 from 307, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
The number 90 fits into 370 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 6123.4
The remainder is 10 after subtracting 360 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
90 goes into 100 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 6123.41
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 6123.411
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 6123.411 with a balance of 0.001.
