We're dividing 21935451 by 397 
We want to divide 21935451 by 397.

Moving on to step 1:
The number 397 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 397

On to step 2:
397 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
Deduct 0 from 21 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 397

Moving on to step 3:
397 goes into 219 0 times with a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Bring next digit (3) of the dividend behind the 219 and repeat the process: 2193 / 397

Moving on to step 4:
When dividing 2193 by 397, we get 5 with a remainder of 208.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 1985 from 2193 to get 208.
Fetch the next digit (5) from the dividend, attach it to 208 and continue: 2085 / 397

Going ahead to step 5:
The number 397 fits into 2085 5 times, leaving a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 55.0
If we subtract 1985 from 2085, we get 100.
Bring next digit (4) of the dividend behind the 100 and repeat the process: 1004 / 397

Advancing to step 6:
If we divide 1004 by 397, we get 2 and a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 552.0
Subtract 794 from 1004 to get 210.
Bring next digit (5) of the dividend behind the 210 and repeat the process: 2105 / 397

Let's proceed to step 7:
If we divide 2105 by 397, we get 5 and a remainder of 120.
The next digit of our result is 5. 
Result so far: 5525.0
Subtracting 1985 from 2105 leaves us with 120.
Append the next digit (1) from the dividend to 120 and continue with: 1201 / 397

Going ahead to step 8:
1201 divided by 397 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 55253.0
Subtracting 1191 from 1201 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
397 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 55253.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
397 can be fit into 1000 2 times, resulting in a remainder of 206.
Use 2 as the next digit of our solution. 
Result so far: 55253.02
The remainder is 206 after subtracting 794 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 11:
2060 divided by 397 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 55253.025
The remainder is 75 after subtracting 1985 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 12:
If we divide 750 by 397, we get 1 and a remainder of 353.
The next digit of our result is 1. 
Result so far: 55253.0251
Deduct 397 from 750 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 13:
397 goes into 3530 8 times with a remainder of 354.
Record the quotient 8 as the next digit in the result. 
Result so far: 55253.02518
Deduct 3176 from 3530 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 14:
397 goes into 3540 8 times with a remainder of 364.
Record the quotient 8 as the next digit in the result. 
Result so far: 55253.025188
Subtract 3176 from 3540 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

In conclusion, the division gives 55253.025188 with a balance of 3.64e-05.
