We look at the division of 90940036 by 429 
We want to divide 90940036 by 429.

Step 1:
429 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 429

Let's proceed to step 2:
429 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 429

Let's proceed to step 3:
When dividing 909 by 429, we get 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 858 from 909 leaves us with 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 429

Let's proceed to step 4:
429 can be fit into 514 1 times, resulting in a remainder of 85.
The next digit of our result is 1. 
Result so far: 21.0
Subtracting 429 from 514 leaves us with 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 429

Moving on to step 5:
When dividing 850 by 429, we get 1 with a remainder of 421.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
Subtracting 429 from 850 leaves us with 421.
Take the next digit (0) from the dividend and append it to 421, then repeat: 4210 / 429

Let's proceed to step 6:
4210 divided by 429 is 9 with a remainder of 349.
Write down 9 as next digit of the result. 
Result so far: 2119.0
If we subtract 3861 from 4210, we get 349.
Append the next digit (3) from the dividend to 349 and continue with: 3493 / 429

Moving on to step 7:
When dividing 3493 by 429, we get 8 with a remainder of 61.
The next digit of our result is 8. 
Result so far: 21198.0
Subtract 3432 from 3493 to get 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 429

Step 8:
When dividing 616 by 429, we get 1 with a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 211981.0
The remainder is 187 after subtracting 429 from 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 9:
If we divide 1870 by 429, we get 4 and a remainder of 154.
Write down 4 as next digit of the result. 
Result so far: 211981.4
If we subtract 1716 from 1870, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
429 can be fit into 1540 3 times, resulting in a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 211981.43
Subtract 1287 from 1540 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 11:
429 can be fit into 2530 5 times, resulting in a remainder of 385.
Record the quotient 5 as the next digit in the result. 
Result so far: 211981.435
Subtract 2145 from 2530 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 12:
If we divide 3850 by 429, we get 8 and a remainder of 418.
Use 8 as the next digit of our solution. 
Result so far: 211981.4358
Deduct 3432 from 3850 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 13:
429 can be fit into 4180 9 times, resulting in a remainder of 319.
The next digit of our result is 9. 
Result so far: 211981.43589
Deduct 3861 from 4180 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 14:
429 can be fit into 3190 7 times, resulting in a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 211981.435897
Deduct 3003 from 3190 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 15:
1870 divided by 429 is 4 with a remainder of 154.
Record the quotient 4 as the next digit in the result. 
Result so far: 211981.4358974
Subtract 1716 from 1870 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 16:
429 can be fit into 1540 3 times, resulting in a remainder of 253.
The number 3 becomes the next digit in our result. 
Result so far: 211981.43589743
Subtracting 1287 from 1540 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

After the division, we end up with 211981.43589743 and a remainder of 2.53e-07.
