97630848 divided by 642 
We want to divide 97630848 by 642.

Step 1:
The number 642 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 642

Step 2:
When dividing 97 by 642, we get 0 with a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Fetch the next digit (6) from the dividend, attach it to 97 and continue: 976 / 642

Advancing to step 3:
642 goes into 976 1 times with a remainder of 334.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 642 from 976 and we're left with 334.
Bring next digit (3) of the dividend behind the 334 and repeat the process: 3343 / 642

Advancing to step 4:
The number 642 fits into 3343 5 times, leaving a remainder of 133.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 133 after subtracting 3210 from 3343.
Fetch the next digit (0) from the dividend, attach it to 133 and continue: 1330 / 642

On to step 5:
642 can be fit into 1330 2 times, resulting in a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtracting 1284 from 1330 leaves us with 46.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 642

Let's proceed to step 6:
If we divide 468 by 642, we get 0 and a remainder of 468.
Write down 0 as next digit of the result. 
Result so far: 1520.0
Deduct 0 from 468 and we're left with 468.
Append the next digit (4) from the dividend to 468 and continue with: 4684 / 642

Advancing to step 7:
When dividing 4684 by 642, we get 7 with a remainder of 190.
Use 7 as the next digit of our solution. 
Result so far: 15207.0
If we subtract 4494 from 4684, we get 190.
Grab the next digit (8) from the dividend, add it to 190, then carry on: 1908 / 642

Moving on to step 8:
If we divide 1908 by 642, we get 2 and a remainder of 624.
The number 2 becomes the next digit in our result. 
Result so far: 152072.0
Subtract 1284 from 1908 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 9:
If we divide 6240 by 642, we get 9 and a remainder of 462.
Put 9 as the next digit of the answer. 
Result so far: 152072.9
Subtract 5778 from 6240 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 10:
If we divide 4620 by 642, we get 7 and a remainder of 126.
The number 7 becomes the next digit in our result. 
Result so far: 152072.97
If we take 4494 away from 4620, we end up 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.

On to step 11:
1260 divided by 642 is 1 with a remainder of 618.
Record the quotient 1 as the next digit in the result. 
Result so far: 152072.971
The remainder is 618 after subtracting 642 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 12:
642 goes into 6180 9 times with a remainder of 402.
The next digit of our result is 9. 
Result so far: 152072.9719
Subtracting 5778 from 6180 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 13:
The number 642 fits into 4020 6 times, leaving a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 152072.97196
Subtracting 3852 from 4020 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 14:
If we divide 1680 by 642, we get 2 and a remainder of 396.
Put 2 as the next digit of the answer. 
Result so far: 152072.971962
Subtracting 1284 from 1680 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 15:
The number 642 fits into 3960 6 times, leaving a remainder of 108.
Write down 6 as next digit of the result. 
Result so far: 152072.9719626
Subtracting 3852 from 3960 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 16:
If we divide 1080 by 642, we get 1 and a remainder of 438.
Put 1 as the next digit of the answer. 
Result so far: 152072.97196261
Subtract 642 from 1080 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final outcome is 152072.97196261, with a leftover of 4.38e-07.
