We're dividing 90534222 by 210 
Our goal is to divide 90534222 by 210.

Let's proceed to step 1:
The number 210 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
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 / 210

Moving on to step 2:
90 divided by 210 is 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 210

Going ahead to step 3:
The number 210 fits into 905 4 times, leaving a remainder of 65.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 840 from 905 and we're left with 65.
Include the next digit (3) from the dividend after 65, then repeat: 653 / 210

Let's proceed to step 4:
The number 210 fits into 653 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 630 away from 653, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 210

On to step 5:
The number 210 fits into 234 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 431.0
Deduct 210 from 234 and we're left with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 210

Moving on to step 6:
If we divide 242 by 210, we get 1 and a remainder of 32.
The next digit of our result is 1. 
Result so far: 4311.0
Subtracting 210 from 242 leaves us with 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 210

Advancing to step 7:
210 goes into 322 1 times with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 43111.0
Deduct 210 from 322 and we're left with 112.
Append the next digit (2) from the dividend to 112 and continue with: 1122 / 210

Moving on to step 8:
1122 divided by 210 is 5 with a remainder of 72.
The next digit of our result is 5. 
Result so far: 431115.0
If we take 1050 away from 1122, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
210 can be fit into 720 3 times, resulting in a remainder of 90.
Record the quotient 3 as the next digit in the result. 
Result so far: 431115.3
If we take 630 away from 720, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
900 divided by 210 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 431115.34
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 210, we get 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 431115.342
Subtract 420 from 600 to get 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 12:
1800 divided by 210 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 431115.3428
Subtract 1680 from 1800 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
When dividing 1200 by 210, we get 5 with a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 431115.34285
Deduct 1050 from 1200 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 14:
If we divide 1500 by 210, we get 7 and a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 431115.342857
If we take 1470 away from 1500, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 15:
210 can be fit into 300 1 times, resulting in a remainder of 90.
The next digit of our result is 1. 
Result so far: 431115.3428571
Deduct 210 from 300 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 16:
900 divided by 210 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 431115.34285714
Subtract 840 from 900 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 431115.34285714, and the remainder is 6e-08.
