Let's divide 64570869 by 155
We want to figure out the number of times 64570869 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
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 155

Step 2:
64 divided by 155 is 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 155

Step 3:
When dividing 645 by 155, we get 4 with a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 620 from 645 to get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 155

On to step 4:
When dividing 257 by 155, we get 1 with a remainder of 102.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 102 after subtracting 155 from 257.
Bring next digit (0) of the dividend behind the 102 and repeat the process: 1020 / 155

Going ahead to step 5:
1020 divided by 155 is 6 with a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Deduct 930 from 1020 and we're left with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 155

Going ahead to step 6:
155 can be fit into 908 5 times, resulting in a remainder of 133.
The number 5 becomes the next digit in our result. 
Result so far: 4165.0
Deduct 775 from 908 and we're left with 133.
Take the next digit (6) from the dividend and append it to 133, then repeat: 1336 / 155

Advancing to step 7:
If we divide 1336 by 155, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 41658.0
Deduct 1240 from 1336 and we're left with 96.
Fetch the next digit (9) from the dividend, attach it to 96 and continue: 969 / 155

On to step 8:
When dividing 969 by 155, we get 6 with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 416586.0
Subtracting 930 from 969 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
155 goes into 390 2 times with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 416586.2
Subtract 310 from 390 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
155 goes into 800 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 416586.25
If we subtract 775 from 800, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
If we divide 250 by 155, we get 1 and a remainder of 95.
Put 1 as the next digit of the answer. 
Result so far: 416586.251
Subtracting 155 from 250 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 12:
The number 155 fits into 950 6 times, leaving a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 416586.2516
If we subtract 930 from 950, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
155 goes into 200 1 times with a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 416586.25161
The remainder is 45 after subtracting 155 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
The number 155 fits into 450 2 times, leaving a remainder of 140.
The next digit of our result is 2. 
Result so far: 416586.251612
The remainder is 140 after subtracting 310 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
The number 155 fits into 1400 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 416586.2516129
The remainder is 5 after subtracting 1395 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 16:
155 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 416586.2516129
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 416586.2516129, and the remainder is 5e-08.
