We look at the division of 16505583 by 641 
Our goal is to divide 16505583 by 641.

Going ahead to step 1:
641 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 641

Moving on to step 2:
16 divided by 641 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 641

Let's proceed to step 3:
If we divide 165 by 641, we get 0 and a remainder of 165.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 165 to get 165.
Grab the next digit (0) from the dividend, add it to 165, then carry on: 1650 / 641

Step 4:
641 goes into 1650 2 times with a remainder of 368.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 368 after subtracting 1282 from 1650.
Grab the next digit (5) from the dividend, add it to 368, then carry on: 3685 / 641

Advancing to step 5:
The number 641 fits into 3685 5 times, leaving a remainder of 480.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 3205 from 3685 and we're left with 480.
Grab the next digit (5) from the dividend, add it to 480, then carry on: 4805 / 641

Step 6:
When dividing 4805 by 641, we get 7 with a remainder of 318.
Record the quotient 7 as the next digit in the result. 
Result so far: 257.0
Subtract 4487 from 4805 to get 318.
Grab the next digit (8) from the dividend, add it to 318, then carry on: 3188 / 641

Moving on to step 7:
3188 divided by 641 is 4 with a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 2574.0
The remainder is 624 after subtracting 2564 from 3188.
Append the next digit (3) from the dividend to 624 and continue with: 6243 / 641

Let's proceed to step 8:
If we divide 6243 by 641, we get 9 and a remainder of 474.
Write down 9 as next digit of the result. 
Result so far: 25749.0
Subtract 5769 from 6243 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 9:
4740 divided by 641 is 7 with a remainder of 253.
Write down 7 as next digit of the result. 
Result so far: 25749.7
Subtract 4487 from 4740 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 10:
The number 641 fits into 2530 3 times, leaving a remainder of 607.
Put 3 as the next digit of the answer. 
Result so far: 25749.73
If we take 1923 away from 2530, we end up with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Step 11:
641 goes into 6070 9 times with a remainder of 301.
Record the quotient 9 as the next digit in the result. 
Result so far: 25749.739
Subtract 5769 from 6070 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Let's proceed to step 12:
If we divide 3010 by 641, we get 4 and a remainder of 446.
Write down 4 as next digit of the result. 
Result so far: 25749.7394
Deduct 2564 from 3010 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 13:
When dividing 4460 by 641, we get 6 with a remainder of 614.
The number 6 becomes the next digit in our result. 
Result so far: 25749.73946
Subtracting 3846 from 4460 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 14:
641 can be fit into 6140 9 times, resulting in a remainder of 371.
Write down 9 as next digit of the result. 
Result so far: 25749.739469
If we subtract 5769 from 6140, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Advancing to step 15:
3710 divided by 641 is 5 with a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 25749.7394695
Deduct 3205 from 3710 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 16:
641 can be fit into 5050 7 times, resulting in a remainder of 563.
Use 7 as the next digit of our solution. 
Result so far: 25749.73946957
If we subtract 4487 from 5050, we get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

The final outcome is 25749.73946957, with a leftover of 5.63e-07.
