We're dividing 90690861 by 214 
Our goal is to divide 90690861 by 214.

On to step 1:
214 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 214

Step 2:
If we divide 90 by 214, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 214

Going ahead to step 3:
214 can be fit into 906 4 times, resulting in a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 856 from 906, we get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 214

On to step 4:
214 goes into 509 2 times with a remainder of 81.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 428 from 509 leaves us with 81.
Append the next digit (0) from the dividend to 81 and continue with: 810 / 214

Moving on to step 5:
214 goes into 810 3 times with a remainder of 168.
Put 3 as the next digit of the answer. 
Result so far: 423.0
If we take 642 away from 810, we end up with 168.
Take the next digit (8) from the dividend and append it to 168, then repeat: 1688 / 214

On to step 6:
214 can be fit into 1688 7 times, resulting in a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 4237.0
If we take 1498 away from 1688, we end up with 190.
Bring next digit (6) of the dividend behind the 190 and repeat the process: 1906 / 214

Moving on to step 7:
214 goes into 1906 8 times with a remainder of 194.
The next digit of our result is 8. 
Result so far: 42378.0
Deduct 1712 from 1906 and we're left with 194.
Append the next digit (1) from the dividend to 194 and continue with: 1941 / 214

Step 8:
If we divide 1941 by 214, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 423789.0
If we subtract 1926 from 1941, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
214 can be fit into 150 0 times, resulting in a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 423789.0
Subtracting 0 from 150 leaves us 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.

On to step 10:
If we divide 1500 by 214, we get 7 and a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 423789.07
Subtract 1498 from 1500 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
The number 214 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 423789.07
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
214 goes into 200 0 times with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 423789.07
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 423789.07 with a remaining 0.002.
