29635639 ÷ 642 
We want to divide 29635639 by 642.

Let's proceed to step 1:
The number 642 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 642

Moving on to step 2:
If we divide 29 by 642, we get 0 and a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 642

Let's proceed to step 3:
642 can be fit into 296 0 times, resulting in a remainder of 296.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 296, we get 296.
Fetch the next digit (3) from the dividend, attach it to 296 and continue: 2963 / 642

Advancing to step 4:
642 can be fit into 2963 4 times, resulting in a remainder of 395.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2568 from 2963 to get 395.
Include the next digit (5) from the dividend after 395, then repeat: 3955 / 642

Moving on to step 5:
3955 divided by 642 is 6 with a remainder of 103.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 3852 from 3955, we get 103.
Fetch the next digit (6) from the dividend, attach it to 103 and continue: 1036 / 642

Let's proceed to step 6:
642 can be fit into 1036 1 times, resulting in a remainder of 394.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
If we take 642 away from 1036, we end up with 394.
Append the next digit (3) from the dividend to 394 and continue with: 3943 / 642

On to step 7:
When dividing 3943 by 642, we get 6 with a remainder of 91.
Write down 6 as next digit of the result. 
Result so far: 4616.0
Deduct 3852 from 3943 and we're left with 91.
Bring next digit (9) of the dividend behind the 91 and repeat the process: 919 / 642

Let's proceed to step 8:
If we divide 919 by 642, we get 1 and a remainder of 277.
The number 1 becomes the next digit in our result. 
Result so far: 46161.0
Deduct 642 from 919 and we're left with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 9:
If we divide 2770 by 642, we get 4 and a remainder of 202.
Use 4 as the next digit of our solution. 
Result so far: 46161.4
If we subtract 2568 from 2770, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Step 10:
2020 divided by 642 is 3 with a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 46161.43
If we take 1926 away from 2020, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
642 goes into 940 1 times with a remainder of 298.
The number 1 becomes the next digit in our result. 
Result so far: 46161.431
Subtracting 642 from 940 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 12:
642 goes into 2980 4 times with a remainder of 412.
Record the quotient 4 as the next digit in the result. 
Result so far: 46161.4314
The remainder is 412 after subtracting 2568 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 13:
The number 642 fits into 4120 6 times, leaving a remainder of 268.
Record the quotient 6 as the next digit in the result. 
Result so far: 46161.43146
If we take 3852 away from 4120, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 14:
The number 642 fits into 2680 4 times, leaving a remainder of 112.
Use 4 as the next digit of our solution. 
Result so far: 46161.431464
Subtracting 2568 from 2680 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 15:
The number 642 fits into 1120 1 times, leaving a remainder of 478.
Use 1 as the next digit of our solution. 
Result so far: 46161.4314641
If we subtract 642 from 1120, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Going ahead to step 16:
If we divide 4780 by 642, we get 7 and a remainder of 286.
Record the quotient 7 as the next digit in the result. 
Result so far: 46161.43146417
The remainder is 286 after subtracting 4494 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

After the division, we end up with 46161.43146417 and a remainder of 2.86e-07.
