51906293 ÷ 64 
We want to figure out the number of times 51906293 can be divided by 64.

Moving on to step 1:
When dividing 5 by 64, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 64

Let's proceed to step 2:
If we divide 51 by 64, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 64

Let's proceed to step 3:
If we divide 519 by 64, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 512 from 519 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 64

Moving on to step 4:
When dividing 70 by 64, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we subtract 64 from 70, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 64

Step 5:
64 can be fit into 66 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 811.0
Subtract 64 from 66 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 64

Moving on to step 6:
If we divide 22 by 64, we get 0 and a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 8110.0
If we subtract 0 from 22, we get 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 64

Going ahead to step 7:
If we divide 229 by 64, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 81103.0
Subtract 192 from 229 to get 37.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 64

Going ahead to step 8:
64 can be fit into 373 5 times, resulting in a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 811035.0
Deduct 320 from 373 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
The number 64 fits into 530 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 811035.8
The remainder is 18 after subtracting 512 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
The number 64 fits into 180 2 times, leaving a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 811035.82
Subtracting 128 from 180 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
If we divide 520 by 64, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 811035.828
Subtracting 512 from 520 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
When dividing 80 by 64, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 811035.8281
The remainder is 16 after subtracting 64 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
64 goes into 160 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 811035.82812
If we subtract 128 from 160, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
When dividing 320 by 64, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 811035.828125
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 15:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 811035.828125
If we take 0 away from 0, 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 16:
If we divide 0 by 64, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 811035.828125
Subtracting 0 from 0 leaves us 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.

Our division results in 811035.828125 with a remaining 0.0.
