697398 ÷ 51 
Let's see how many times 51 fits into 697398.

Going ahead to step 1:
6 divided by 51 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 51

Moving on to step 2:
If we divide 69 by 51, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 51 from 69, we get 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 51

Let's proceed to step 3:
When dividing 187 by 51, we get 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 153 from 187 to get 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 51

On to step 4:
51 can be fit into 343 6 times, resulting in a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
The remainder is 37 after subtracting 306 from 343.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 51

On to step 5:
If we divide 379 by 51, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 1367.0
Subtract 357 from 379 to get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 51

On to step 6:
When dividing 228 by 51, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 13674.0
Subtracting 204 from 228 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
51 goes into 240 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 13674.4
If we take 204 away from 240, we end up 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.

Advancing to step 8:
If we divide 360 by 51, we get 7 and a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 13674.47
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
If we divide 30 by 51, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13674.47
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
If we divide 300 by 51, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 13674.4705
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
When dividing 450 by 51, we get 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 13674.47058
Deduct 408 from 450 and we're left 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 12:
51 can be fit into 420 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 13674.470588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 13674.470588 with a remainder of 1.2e-06.
