Let's divide 13228769 by 641
We want to divide 13228769 by 641.

Going ahead to step 1:
1 divided by 641 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 641

On to step 2:
When dividing 13 by 641, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 641

Let's proceed to step 3:
The number 641 fits into 132 0 times, leaving a remainder of 132.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Grab the next digit (2) from the dividend, add it to 132, then carry on: 1322 / 641

Moving on to step 4:
The number 641 fits into 1322 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1282 from 1322 and we're left with 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 641

Going ahead to step 5:
641 goes into 408 0 times with a remainder of 408.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 408, we end up with 408.
Grab the next digit (7) from the dividend, add it to 408, then carry on: 4087 / 641

On to step 6:
When dividing 4087 by 641, we get 6 with a remainder of 241.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
Subtract 3846 from 4087 to get 241.
Include the next digit (6) from the dividend after 241, then repeat: 2416 / 641

Moving on to step 7:
If we divide 2416 by 641, we get 3 and a remainder of 493.
Use 3 as the next digit of our solution. 
Result so far: 2063.0
Deduct 1923 from 2416 and we're left with 493.
Append the next digit (9) from the dividend to 493 and continue with: 4939 / 641

Let's proceed to step 8:
If we divide 4939 by 641, we get 7 and a remainder of 452.
Write down 7 as next digit of the result. 
Result so far: 20637.0
The remainder is 452 after subtracting 4487 from 4939.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 9:
4520 divided by 641 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 20637.7
Subtract 4487 from 4520 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
If we divide 330 by 641, we get 0 and a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 20637.7
If we take 0 away from 330, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 11:
When dividing 3300 by 641, we get 5 with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 20637.705
If we subtract 3205 from 3300, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 12:
When dividing 950 by 641, we get 1 with a remainder of 309.
Write down 1 as next digit of the result. 
Result so far: 20637.7051
If we take 641 away from 950, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 13:
If we divide 3090 by 641, we get 4 and a remainder of 526.
Write down 4 as next digit of the result. 
Result so far: 20637.70514
Deduct 2564 from 3090 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 14:
5260 divided by 641 is 8 with a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 20637.705148
If we subtract 5128 from 5260, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 15:
641 can be fit into 1320 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 20637.7051482
If we subtract 1282 from 1320, 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.

Step 16:
If we divide 380 by 641, we get 0 and a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 20637.7051482
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The quotient of the division is 20637.7051482, and the remainder is 3.8e-07.
