400696 ÷ 51 
We're looking to find how many times 51 goes into 400696.

Step 1:
51 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 51

Let's proceed to step 2:
If we divide 40 by 51, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 51

Let's proceed to step 3:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 357 from 400 leaves us with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 51

Moving on to step 4:
If we divide 436 by 51, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 408 from 436 leaves us with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 51

On to step 5:
51 goes into 289 5 times with a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 785.0
If we take 255 away from 289, we end up with 34.
Bring next digit (6) of the dividend behind the 34 and repeat the process: 346 / 51

Let's proceed to step 6:
The number 51 fits into 346 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 7856.0
Subtracting 306 from 346 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 51, we get 7 and a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 7856.7
Deduct 357 from 400 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
430 divided by 51 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 7856.78
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7856.784
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
160 divided by 51 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 7856.7843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
51 goes into 70 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 7856.78431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
If we divide 190 by 51, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 7856.784313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
370 divided by 51 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7856.7843137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 14:
When dividing 130 by 51, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7856.78431372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 7856.78431372 and a remainder of 2.8e-08.
