We're dividing 97389641 by 642 
Let's see how many times 642 fits into 97389641.

Let's proceed to step 1:
The number 642 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 642

Step 2:
The number 642 fits into 97 0 times, leaving a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 642

Advancing to step 3:
If we divide 973 by 642, we get 1 and a remainder of 331.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 331 after subtracting 642 from 973.
Append the next digit (8) from the dividend to 331 and continue with: 3318 / 642

Moving on to step 4:
3318 divided by 642 is 5 with a remainder of 108.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 3210 from 3318 to get 108.
Grab the next digit (9) from the dividend, add it to 108, then carry on: 1089 / 642

On to step 5:
1089 divided by 642 is 1 with a remainder of 447.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtracting 642 from 1089 leaves us with 447.
Take the next digit (6) from the dividend and append it to 447, then repeat: 4476 / 642

Going ahead to step 6:
642 goes into 4476 6 times with a remainder of 624.
Write down 6 as next digit of the result. 
Result so far: 1516.0
Deduct 3852 from 4476 and we're left with 624.
Bring next digit (4) of the dividend behind the 624 and repeat the process: 6244 / 642

On to step 7:
642 goes into 6244 9 times with a remainder of 466.
Put 9 as the next digit of the answer. 
Result so far: 15169.0
The remainder is 466 after subtracting 5778 from 6244.
Take the next digit (1) from the dividend and append it to 466, then repeat: 4661 / 642

Moving on to step 8:
4661 divided by 642 is 7 with a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 151697.0
The remainder is 167 after subtracting 4494 from 4661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 9:
642 goes into 1670 2 times with a remainder of 386.
Use 2 as the next digit of our solution. 
Result so far: 151697.2
Deduct 1284 from 1670 and we're left with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Moving on to step 10:
The number 642 fits into 3860 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 151697.26
If we take 3852 away from 3860, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 642 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 151697.26
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
642 can be fit into 800 1 times, resulting in a remainder of 158.
Write down 1 as next digit of the result. 
Result so far: 151697.2601
Subtract 642 from 800 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 13:
When dividing 1580 by 642, we get 2 with a remainder of 296.
The next digit of our result is 2. 
Result so far: 151697.26012
If we take 1284 away from 1580, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 14:
2960 divided by 642 is 4 with a remainder of 392.
The number 4 becomes the next digit in our result. 
Result so far: 151697.260124
If we take 2568 away from 2960, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 15:
3920 divided by 642 is 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 151697.2601246
Subtracting 3852 from 3920 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 16:
When dividing 680 by 642, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 151697.26012461
If we subtract 642 from 680, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 151697.26012461 with a remaining 3.8e-08.
