43353908 divided by 641 
We want to divide 43353908 by 641.

On to step 1:
The number 641 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 641

On to step 2:
When dividing 43 by 641, we get 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 641

Advancing to step 3:
433 divided by 641 is 0 with a remainder of 433.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 433 to get 433.
Fetch the next digit (5) from the dividend, attach it to 433 and continue: 4335 / 641

Advancing to step 4:
4335 divided by 641 is 6 with a remainder of 489.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 3846 from 4335 and we're left with 489.
Grab the next digit (3) from the dividend, add it to 489, then carry on: 4893 / 641

Going ahead to step 5:
4893 divided by 641 is 7 with a remainder of 406.
Use 7 as the next digit of our solution. 
Result so far: 67.0
If we subtract 4487 from 4893, we get 406.
Grab the next digit (9) from the dividend, add it to 406, then carry on: 4069 / 641

Advancing to step 6:
641 can be fit into 4069 6 times, resulting in a remainder of 223.
Write down 6 as next digit of the result. 
Result so far: 676.0
Subtracting 3846 from 4069 leaves us with 223.
Take the next digit (0) from the dividend and append it to 223, then repeat: 2230 / 641

Going ahead to step 7:
2230 divided by 641 is 3 with a remainder of 307.
Use 3 as the next digit of our solution. 
Result so far: 6763.0
If we take 1923 away from 2230, we end up with 307.
Append the next digit (8) from the dividend to 307 and continue with: 3078 / 641

Moving on to step 8:
The number 641 fits into 3078 4 times, leaving a remainder of 514.
The next digit of our result is 4. 
Result so far: 67634.0
Deduct 2564 from 3078 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Advancing to step 9:
641 can be fit into 5140 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 67634.8
Deduct 5128 from 5140 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
When dividing 120 by 641, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 67634.8
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
1200 divided by 641 is 1 with a remainder of 559.
Record the quotient 1 as the next digit in the result. 
Result so far: 67634.801
Subtracting 641 from 1200 leaves us with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Going ahead to step 12:
When dividing 5590 by 641, we get 8 with a remainder of 462.
Write down 8 as next digit of the result. 
Result so far: 67634.8018
If we subtract 5128 from 5590, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 13:
The number 641 fits into 4620 7 times, leaving a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 67634.80187
Subtract 4487 from 4620 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 14:
The number 641 fits into 1330 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 67634.801872
If we subtract 1282 from 1330, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 15:
If we divide 480 by 641, we get 0 and a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 67634.801872
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 16:
The number 641 fits into 4800 7 times, leaving a remainder of 313.
Put 7 as the next digit of the answer. 
Result so far: 67634.80187207
If we take 4487 away from 4800, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

The quotient of the division is 67634.80187207, and the remainder is 3.13e-07.
