2190311 ÷ 397 
Let's see how many times 397 fits into 2190311.

Going ahead to step 1:
The number 397 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 397

Moving on to step 2:
397 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 397

Let's proceed to step 3:
397 can be fit into 219 0 times, resulting in a remainder of 219.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 397

Step 4:
If we divide 2190 by 397, we get 5 and a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 1985 from 2190, we get 205.
Fetch the next digit (3) from the dividend, attach it to 205 and continue: 2053 / 397

Going ahead to step 5:
2053 divided by 397 is 5 with a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 1985 from 2053 to get 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 397

Let's proceed to step 6:
681 divided by 397 is 1 with a remainder of 284.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
If we subtract 397 from 681, we get 284.
Include the next digit (1) from the dividend after 284, then repeat: 2841 / 397

Advancing to step 7:
397 goes into 2841 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 5517.0
Deduct 2779 from 2841 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
397 can be fit into 620 1 times, resulting in a remainder of 223.
Put 1 as the next digit of the answer. 
Result so far: 5517.1
Subtract 397 from 620 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 9:
The number 397 fits into 2230 5 times, leaving a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 5517.15
Subtracting 1985 from 2230 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 10:
When dividing 2450 by 397, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 5517.156
Subtract 2382 from 2450 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
397 goes into 680 1 times with a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 5517.1561
Subtracting 397 from 680 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 12:
2830 divided by 397 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 5517.15617
If we subtract 2779 from 2830, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 13:
397 goes into 510 1 times with a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 5517.156171
The remainder is 113 after subtracting 397 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 14:
When dividing 1130 by 397, we get 2 with a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 5517.1561712
Deduct 794 from 1130 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 15:
If we divide 3360 by 397, we get 8 and a remainder of 184.
Use 8 as the next digit of our solution. 
Result so far: 5517.15617128
The remainder is 184 after subtracting 3176 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final outcome is 5517.15617128, with a leftover of 1.84e-07.
