39645101 divided by 402 
We want to figure out the number of times 39645101 can be divided by 402.

On to step 1:
402 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 402

Moving on to step 2:
39 divided by 402 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 402

Step 3:
The number 402 fits into 396 0 times, leaving a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 396, we get 396.
Append the next digit (4) from the dividend to 396 and continue with: 3964 / 402

Let's proceed to step 4:
The number 402 fits into 3964 9 times, leaving a remainder of 346.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 3618 from 3964, we get 346.
Include the next digit (5) from the dividend after 346, then repeat: 3465 / 402

Advancing to step 5:
If we divide 3465 by 402, we get 8 and a remainder of 249.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 3216 from 3465 leaves us with 249.
Bring next digit (1) of the dividend behind the 249 and repeat the process: 2491 / 402

Advancing to step 6:
If we divide 2491 by 402, we get 6 and a remainder of 79.
Use 6 as the next digit of our solution. 
Result so far: 986.0
The remainder is 79 after subtracting 2412 from 2491.
Fetch the next digit (0) from the dividend, attach it to 79 and continue: 790 / 402

Advancing to step 7:
When dividing 790 by 402, we get 1 with a remainder of 388.
Put 1 as the next digit of the answer. 
Result so far: 9861.0
If we subtract 402 from 790, we get 388.
Append the next digit (1) from the dividend to 388 and continue with: 3881 / 402

Advancing to step 8:
When dividing 3881 by 402, we get 9 with a remainder of 263.
Write down 9 as next digit of the result. 
Result so far: 98619.0
Subtracting 3618 from 3881 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
402 goes into 2630 6 times with a remainder of 218.
Write down 6 as next digit of the result. 
Result so far: 98619.6
If we subtract 2412 from 2630, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 10:
The number 402 fits into 2180 5 times, leaving a remainder of 170.
The next digit of our result is 5. 
Result so far: 98619.65
Subtract 2010 from 2180 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 11:
If we divide 1700 by 402, we get 4 and a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 98619.654
If we take 1608 away from 1700, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
When dividing 920 by 402, we get 2 with a remainder of 116.
The next digit of our result is 2. 
Result so far: 98619.6542
The remainder is 116 after subtracting 804 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 13:
When dividing 1160 by 402, we get 2 with a remainder of 356.
Use 2 as the next digit of our solution. 
Result so far: 98619.65422
If we subtract 804 from 1160, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The final outcome is 98619.65422, with a leftover of 0.000356.
