We're dividing 3525551 by 641 
We want to divide 3525551 by 641.

On to step 1:
3 divided by 641 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 641

Advancing to step 2:
641 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 641

On to step 3:
When dividing 352 by 641, we get 0 with a remainder of 352.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 352 to get 352.
Fetch the next digit (5) from the dividend, attach it to 352 and continue: 3525 / 641

Moving on to step 4:
When dividing 3525 by 641, we get 5 with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 3205 from 3525 to get 320.
Fetch the next digit (5) from the dividend, attach it to 320 and continue: 3205 / 641

Step 5:
641 can be fit into 3205 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 3205 from 3205, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 641

Let's proceed to step 6:
The number 641 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 550.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 641

Going ahead to step 7:
When dividing 51 by 641, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 5500.0
If we take 0 away from 51, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
641 can be fit into 510 0 times, resulting in a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 5500.0
If we take 0 away from 510, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 9:
641 goes into 5100 7 times with a remainder of 613.
Put 7 as the next digit of the answer. 
Result so far: 5500.07
Deduct 4487 from 5100 and we're left with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Advancing to step 10:
641 can be fit into 6130 9 times, resulting in a remainder of 361.
The next digit of our result is 9. 
Result so far: 5500.079
If we subtract 5769 from 6130, we get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 11:
When dividing 3610 by 641, we get 5 with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 5500.0795
If we subtract 3205 from 3610, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 12:
If we divide 4050 by 641, we get 6 and a remainder of 204.
The number 6 becomes the next digit in our result. 
Result so far: 5500.07956
Deduct 3846 from 4050 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 13:
The number 641 fits into 2040 3 times, leaving a remainder of 117.
The next digit of our result is 3. 
Result so far: 5500.079563
Subtract 1923 from 2040 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 14:
641 can be fit into 1170 1 times, resulting in a remainder of 529.
The number 1 becomes the next digit in our result. 
Result so far: 5500.0795631
Subtract 641 from 1170 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Going ahead to step 15:
641 can be fit into 5290 8 times, resulting in a remainder of 162.
The next digit of our result is 8. 
Result so far: 5500.07956318
If we subtract 5128 from 5290, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The quotient of the division is 5500.07956318, and the remainder is 1.62e-07.
