We're dividing 35186433 by 641 
We want to figure out the number of times 35186433 can be divided by 641.

Step 1:
The number 641 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 641

Moving on to step 2:
If we divide 35 by 641, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 641

On to step 3:
641 can be fit into 351 0 times, resulting in a remainder of 351.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 351, we get 351.
Bring next digit (8) of the dividend behind the 351 and repeat the process: 3518 / 641

Let's proceed to step 4:
If we divide 3518 by 641, we get 5 and a remainder of 313.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 3205 from 3518 to get 313.
Bring next digit (6) of the dividend behind the 313 and repeat the process: 3136 / 641

Let's proceed to step 5:
If we divide 3136 by 641, we get 4 and a remainder of 572.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtracting 2564 from 3136 leaves us with 572.
Bring next digit (4) of the dividend behind the 572 and repeat the process: 5724 / 641

Going ahead to step 6:
If we divide 5724 by 641, we get 8 and a remainder of 596.
Write down 8 as next digit of the result. 
Result so far: 548.0
Subtracting 5128 from 5724 leaves us with 596.
Fetch the next digit (3) from the dividend, attach it to 596 and continue: 5963 / 641

Moving on to step 7:
641 can be fit into 5963 9 times, resulting in a remainder of 194.
The number 9 becomes the next digit in our result. 
Result so far: 5489.0
Subtract 5769 from 5963 to get 194.
Take the next digit (3) from the dividend and append it to 194, then repeat: 1943 / 641

Advancing to step 8:
The number 641 fits into 1943 3 times, leaving a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 54893.0
If we subtract 1923 from 1943, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
641 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 54893.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
The number 641 fits into 2000 3 times, leaving a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 54893.03
If we take 1923 away from 2000, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
641 goes into 770 1 times with a remainder of 129.
Use 1 as the next digit of our solution. 
Result so far: 54893.031
If we take 641 away from 770, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 12:
When dividing 1290 by 641, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 54893.0312
The remainder is 8 after subtracting 1282 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
641 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 54893.0312
Subtract 0 from 80 to 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.

Advancing to step 14:
641 can be fit into 800 1 times, resulting in a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 54893.031201
If we subtract 641 from 800, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 15:
641 can be fit into 1590 2 times, resulting in a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 54893.0312012
Subtract 1282 from 1590 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 16:
The number 641 fits into 3080 4 times, leaving a remainder of 516.
The next digit of our result is 4. 
Result so far: 54893.03120124
The remainder is 516 after subtracting 2564 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

After the division, we end up with 54893.03120124 and a remainder of 5.16e-07.
