We're dividing 68160850 by 641 
Let's see how many times 641 fits into 68160850.

Step 1:
When dividing 6 by 641, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 641

Step 2:
The number 641 fits into 68 0 times, leaving a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 641

Going ahead to step 3:
The number 641 fits into 681 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 641 from 681 and we're left with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 641

Going ahead to step 4:
When dividing 406 by 641, we get 0 with a remainder of 406.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 406 after subtracting 0 from 406.
Fetch the next digit (0) from the dividend, attach it to 406 and continue: 4060 / 641

Advancing to step 5:
When dividing 4060 by 641, we get 6 with a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we take 3846 away from 4060, we end up with 214.
Fetch the next digit (8) from the dividend, attach it to 214 and continue: 2148 / 641

Advancing to step 6:
641 can be fit into 2148 3 times, resulting in a remainder of 225.
Use 3 as the next digit of our solution. 
Result so far: 1063.0
If we subtract 1923 from 2148, we get 225.
Take the next digit (5) from the dividend and append it to 225, then repeat: 2255 / 641

On to step 7:
2255 divided by 641 is 3 with a remainder of 332.
The next digit of our result is 3. 
Result so far: 10633.0
Subtract 1923 from 2255 to get 332.
Bring next digit (0) of the dividend behind the 332 and repeat the process: 3320 / 641

Step 8:
The number 641 fits into 3320 5 times, leaving a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 106335.0
If we take 3205 away from 3320, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
641 goes into 1150 1 times with a remainder of 509.
The next digit of our result is 1. 
Result so far: 106335.1
If we take 641 away from 1150, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Going ahead to step 10:
If we divide 5090 by 641, we get 7 and a remainder of 603.
Record the quotient 7 as the next digit in the result. 
Result so far: 106335.17
Subtract 4487 from 5090 to get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Step 11:
The number 641 fits into 6030 9 times, leaving a remainder of 261.
Write down 9 as next digit of the result. 
Result so far: 106335.179
Deduct 5769 from 6030 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 12:
2610 divided by 641 is 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 106335.1794
Subtract 2564 from 2610 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
641 can be fit into 460 0 times, resulting in a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 106335.1794
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 14:
The number 641 fits into 4600 7 times, leaving a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 106335.179407
The remainder is 113 after subtracting 4487 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 15:
When dividing 1130 by 641, we get 1 with a remainder of 489.
Put 1 as the next digit of the answer. 
Result so far: 106335.1794071
Subtract 641 from 1130 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 16:
641 goes into 4890 7 times with a remainder of 403.
Record the quotient 7 as the next digit in the result. 
Result so far: 106335.17940717
The remainder is 403 after subtracting 4487 from 4890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

After the division, we end up with 106335.17940717 and a remainder of 4.03e-07.
