151985 ÷ 64 
We're looking to find how many times 64 goes into 151985.

Step 1:
When dividing 1 by 64, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 64

Let's proceed to step 2:
64 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 64

Let's proceed to step 3:
64 goes into 151 2 times with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 128 from 151 leaves us with 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 64

Moving on to step 4:
If we divide 239 by 64, we get 3 and a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 47 after subtracting 192 from 239.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 64

Moving on to step 5:
When dividing 478 by 64, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 237.0
The remainder is 30 after subtracting 448 from 478.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 64

Moving on to step 6:
If we divide 305 by 64, we get 4 and a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 2374.0
Subtract 256 from 305 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
490 divided by 64 is 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 2374.7
Subtracting 448 from 490 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
The number 64 fits into 420 6 times, leaving a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 2374.76
Subtracting 384 from 420 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
If we divide 360 by 64, we get 5 and a remainder of 40.
The next digit of our result is 5. 
Result so far: 2374.765
Subtract 320 from 360 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
64 goes into 400 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 2374.7656
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 64 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 2374.76562
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2374.765625
If we take 320 away from 320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2374.765625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2374.765625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 2374.765625, with a leftover of 0.0.
