21590821 ÷ 214 
We're looking to find how many times 214 goes into 21590821.

Going ahead to step 1:
214 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 214

On to step 2:
214 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 214

On to step 3:
215 divided by 214 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 214 from 215.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 214

Advancing to step 4:
If we divide 19 by 214, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 214

On to step 5:
When dividing 190 by 214, we get 0 with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 190 after subtracting 0 from 190.
Grab the next digit (8) from the dividend, add it to 190, then carry on: 1908 / 214

Let's proceed to step 6:
If we divide 1908 by 214, we get 8 and a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
Subtracting 1712 from 1908 leaves us with 196.
Fetch the next digit (2) from the dividend, attach it to 196 and continue: 1962 / 214

Advancing to step 7:
1962 divided by 214 is 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 10089.0
Deduct 1926 from 1962 and we're left with 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 214

Going ahead to step 8:
If we divide 361 by 214, we get 1 and a remainder of 147.
The next digit of our result is 1. 
Result so far: 100891.0
The remainder is 147 after subtracting 214 from 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
When dividing 1470 by 214, we get 6 with a remainder of 186.
Write down 6 as next digit of the result. 
Result so far: 100891.6
If we subtract 1284 from 1470, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
1860 divided by 214 is 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 100891.68
If we take 1712 away from 1860, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
1480 divided by 214 is 6 with a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 100891.686
If we take 1284 away from 1480, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 12:
If we divide 1960 by 214, we get 9 and a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 100891.6869
Subtract 1926 from 1960 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
214 can be fit into 340 1 times, resulting in a remainder of 126.
Use 1 as the next digit of our solution. 
Result so far: 100891.68691
Deduct 214 from 340 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 14:
214 can be fit into 1260 5 times, resulting in a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 100891.686915
If we take 1070 away from 1260, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 15:
If we divide 1900 by 214, we get 8 and a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 100891.6869158
Subtracting 1712 from 1900 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 16:
214 can be fit into 1880 8 times, resulting in a remainder of 168.
The next digit of our result is 8. 
Result so far: 100891.68691588
Subtract 1712 from 1880 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 100891.68691588 with a remaining 1.68e-07.
