We're dividing 84197788 by 397 
We want to divide 84197788 by 397.

Let's proceed to step 1:
If we divide 8 by 397, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 397

Advancing to step 2:
84 divided by 397 is 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 397

Moving on to step 3:
If we divide 841 by 397, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 794 from 841 leaves us with 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 397

Let's proceed to step 4:
397 goes into 479 1 times with a remainder of 82.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 82 after subtracting 397 from 479.
Grab the next digit (7) from the dividend, add it to 82, then carry on: 827 / 397

Let's proceed to step 5:
If we divide 827 by 397, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 212.0
Subtract 794 from 827 to get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 397

Step 6:
397 goes into 337 0 times with a remainder of 337.
Record the quotient 0 as the next digit in the result. 
Result so far: 2120.0
The remainder is 337 after subtracting 0 from 337.
Fetch the next digit (8) from the dividend, attach it to 337 and continue: 3378 / 397

Going ahead to step 7:
397 can be fit into 3378 8 times, resulting in a remainder of 202.
Write down 8 as next digit of the result. 
Result so far: 21208.0
Subtract 3176 from 3378 to get 202.
Take the next digit (8) from the dividend and append it to 202, then repeat: 2028 / 397

Let's proceed to step 8:
If we divide 2028 by 397, we get 5 and a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 212085.0
The remainder is 43 after subtracting 1985 from 2028.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
397 goes into 430 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 212085.1
Subtract 397 from 430 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 10:
397 can be fit into 330 0 times, resulting in a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 212085.1
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
397 can be fit into 3300 8 times, resulting in a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 212085.108
Subtract 3176 from 3300 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 12:
397 goes into 1240 3 times with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 212085.1083
Subtracting 1191 from 1240 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
When dividing 490 by 397, we get 1 with a remainder of 93.
Write down 1 as next digit of the result. 
Result so far: 212085.10831
The remainder is 93 after subtracting 397 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 14:
If we divide 930 by 397, we get 2 and a remainder of 136.
Record the quotient 2 as the next digit in the result. 
Result so far: 212085.108312
If we subtract 794 from 930, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 15:
The number 397 fits into 1360 3 times, leaving a remainder of 169.
Write down 3 as next digit of the result. 
Result so far: 212085.1083123
Subtracting 1191 from 1360 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

On to step 16:
397 can be fit into 1690 4 times, resulting in a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 212085.10831234
Deduct 1588 from 1690 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 212085.10831234 and a remainder of 1.02e-07.
