We divide 90519820 by 428
Our goal is to divide 90519820 by 428.

Advancing to step 1:
9 divided by 428 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 428

Going ahead to step 2:
428 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 428

Moving on to step 3:
When dividing 905 by 428, we get 2 with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 856 from 905 leaves us with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 428

Step 4:
428 goes into 491 1 times with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 428 away from 491, we end up with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 428

On to step 5:
639 divided by 428 is 1 with a remainder of 211.
Write down 1 as next digit of the result. 
Result so far: 211.0
Deduct 428 from 639 and we're left with 211.
Append the next digit (8) from the dividend to 211 and continue with: 2118 / 428

Advancing to step 6:
When dividing 2118 by 428, we get 4 with a remainder of 406.
The number 4 becomes the next digit in our result. 
Result so far: 2114.0
Subtracting 1712 from 2118 leaves us with 406.
Include the next digit (2) from the dividend after 406, then repeat: 4062 / 428

Going ahead to step 7:
428 goes into 4062 9 times with a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 21149.0
The remainder is 210 after subtracting 3852 from 4062.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 428

Going ahead to step 8:
If we divide 2100 by 428, we get 4 and a remainder of 388.
Record the quotient 4 as the next digit in the result. 
Result so far: 211494.0
If we subtract 1712 from 2100, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Going ahead to step 9:
428 can be fit into 3880 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 211494.9
Deduct 3852 from 3880 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
The number 428 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 211494.9
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
If we divide 2800 by 428, we get 6 and a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 211494.906
Deduct 2568 from 2800 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
2320 divided by 428 is 5 with a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 211494.9065
If we take 2140 away from 2320, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
The number 428 fits into 1800 4 times, leaving a remainder of 88.
The next digit of our result is 4. 
Result so far: 211494.90654
The remainder is 88 after subtracting 1712 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
428 can be fit into 880 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 211494.906542
The remainder is 24 after subtracting 856 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
428 goes into 240 0 times with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 211494.906542
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
When dividing 2400 by 428, we get 5 with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 211494.90654205
The remainder is 260 after subtracting 2140 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 211494.90654205 with a remainder of 2.6e-07.
