86224479 divided by 642 
We want to divide 86224479 by 642.

Going ahead to step 1:
642 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 642

Step 2:
642 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 642

Moving on to step 3:
642 can be fit into 862 1 times, resulting in a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 642 from 862 leaves us with 220.
Append the next digit (2) from the dividend to 220 and continue with: 2202 / 642

Advancing to step 4:
642 goes into 2202 3 times with a remainder of 276.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1926 from 2202, we get 276.
Grab the next digit (4) from the dividend, add it to 276, then carry on: 2764 / 642

Moving on to step 5:
If we divide 2764 by 642, we get 4 and a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
Deduct 2568 from 2764 and we're left with 196.
Include the next digit (4) from the dividend after 196, then repeat: 1964 / 642

Let's proceed to step 6:
642 can be fit into 1964 3 times, resulting in a remainder of 38.
The next digit of our result is 3. 
Result so far: 1343.0
If we subtract 1926 from 1964, we get 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 642

Step 7:
642 goes into 387 0 times with a remainder of 387.
The number 0 becomes the next digit in our result. 
Result so far: 13430.0
If we take 0 away from 387, we end up with 387.
Fetch the next digit (9) from the dividend, attach it to 387 and continue: 3879 / 642

Step 8:
642 can be fit into 3879 6 times, resulting in a remainder of 27.
Put 6 as the next digit of the answer. 
Result so far: 134306.0
Subtracting 3852 from 3879 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 642, we get 0 and a remainder of 270.
The next digit of our result is 0. 
Result so far: 134306.0
Deduct 0 from 270 and we're left with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
2700 divided by 642 is 4 with a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 134306.04
If we take 2568 away from 2700, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 11:
If we divide 1320 by 642, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 134306.042
If we subtract 1284 from 1320, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
360 divided by 642 is 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 134306.042
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 13:
The number 642 fits into 3600 5 times, leaving a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 134306.04205
Subtract 3210 from 3600 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 14:
The number 642 fits into 3900 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 134306.042056
Subtract 3852 from 3900 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 15:
480 divided by 642 is 0 with a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 134306.042056
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
If we divide 4800 by 642, we get 7 and a remainder of 306.
Record the quotient 7 as the next digit in the result. 
Result so far: 134306.04205607
If we subtract 4494 from 4800, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final outcome is 134306.04205607, with a leftover of 3.06e-07.
