64105216 divided by 155 
We want to figure out the number of times 64105216 can be divided by 155.

On to step 1:
If we divide 6 by 155, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 155

Step 2:
If we divide 64 by 155, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 155

On to step 3:
If we divide 641 by 155, we get 4 and a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 620 from 641 to get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 155

Going ahead to step 4:
The number 155 fits into 210 1 times, leaving a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 55 after subtracting 155 from 210.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 155

On to step 5:
When dividing 555 by 155, we get 3 with a remainder of 90.
The next digit of our result is 3. 
Result so far: 413.0
If we subtract 465 from 555, we get 90.
Take the next digit (2) from the dividend and append it to 90, then repeat: 902 / 155

On to step 6:
When dividing 902 by 155, we get 5 with a remainder of 127.
Record the quotient 5 as the next digit in the result. 
Result so far: 4135.0
Subtracting 775 from 902 leaves us with 127.
Fetch the next digit (1) from the dividend, attach it to 127 and continue: 1271 / 155

Going ahead to step 7:
155 goes into 1271 8 times with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 41358.0
Deduct 1240 from 1271 and we're left with 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 155

Let's proceed to step 8:
When dividing 316 by 155, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 413582.0
The remainder is 6 after subtracting 310 from 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 155, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 413582.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
The number 155 fits into 600 3 times, leaving a remainder of 135.
The next digit of our result is 3. 
Result so far: 413582.03
Subtract 465 from 600 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
155 goes into 1350 8 times with a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 413582.038
Subtract 1240 from 1350 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
1100 divided by 155 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 413582.0387
The remainder is 15 after subtracting 1085 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
155 can be fit into 150 0 times, resulting in a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 413582.0387
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 14:
155 can be fit into 1500 9 times, resulting in a remainder of 105.
Use 9 as the next digit of our solution. 
Result so far: 413582.038709
Subtract 1395 from 1500 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 15:
1050 divided by 155 is 6 with a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 413582.0387096
If we take 930 away from 1050, we end up 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.

On to step 16:
1200 divided by 155 is 7 with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 413582.03870967
If we take 1085 away from 1200, 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.

The final result is 413582.03870967 with a remainder of 1.15e-07.
