90147470 ÷ 209 
Our goal is to divide 90147470 by 209.

Advancing to step 1:
209 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 209

Moving on to step 2:
209 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (1) of the dividend behind the 90 and repeat the process: 901 / 209

On to step 3:
901 divided by 209 is 4 with a remainder of 65.
The next digit of our result is 4. 
Result so far: 4.0
If we take 836 away from 901, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 209

Moving on to step 4:
The number 209 fits into 654 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 627 from 654 leaves us with 27.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 209

Let's proceed to step 5:
If we divide 277 by 209, we get 1 and a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
Subtract 209 from 277 to get 68.
Take the next digit (4) from the dividend and append it to 68, then repeat: 684 / 209

Let's proceed to step 6:
209 goes into 684 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 4313.0
Deduct 627 from 684 and we're left with 57.
Fetch the next digit (7) from the dividend, attach it to 57 and continue: 577 / 209

Let's proceed to step 7:
The number 209 fits into 577 2 times, leaving a remainder of 159.
Put 2 as the next digit of the answer. 
Result so far: 43132.0
Deduct 418 from 577 and we're left with 159.
Bring next digit (0) of the dividend behind the 159 and repeat the process: 1590 / 209

Going ahead to step 8:
The number 209 fits into 1590 7 times, leaving a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 431327.0
Subtracting 1463 from 1590 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
209 can be fit into 1270 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 431327.6
Subtract 1254 from 1270 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 209 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 431327.6
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
If we divide 1600 by 209, we get 7 and a remainder of 137.
Record the quotient 7 as the next digit in the result. 
Result so far: 431327.607
Deduct 1463 from 1600 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 12:
When dividing 1370 by 209, we get 6 with a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 431327.6076
Subtracting 1254 from 1370 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 13:
1160 divided by 209 is 5 with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 431327.60765
If we take 1045 away from 1160, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 14:
When dividing 1150 by 209, we get 5 with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 431327.607655
The remainder is 105 after subtracting 1045 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final result is 431327.607655 with a remainder of 1.05e-05.
