763038 ÷ 51 
We want to figure out the number of times 763038 can be divided by 51.

Advancing to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 51

Advancing to step 2:
The number 51 fits into 76 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 76, we end up with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 51

Step 3:
When dividing 253 by 51, we get 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 204 from 253 and we're left with 49.
Append the next digit (0) from the dividend to 49 and continue with: 490 / 51

On to step 4:
When dividing 490 by 51, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
Subtracting 459 from 490 leaves us with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 51

Moving on to step 5:
51 can be fit into 313 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 1496.0
The remainder is 7 after subtracting 306 from 313.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 51

Moving on to step 6:
51 goes into 78 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 14961.0
Deduct 51 from 78 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
51 goes into 270 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 14961.5
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 51, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 14961.52
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 9:
The number 51 fits into 480 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 14961.529
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
When dividing 210 by 51, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14961.5294
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
When dividing 60 by 51, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 14961.52941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 12:
If we divide 90 by 51, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 14961.529411
Subtract 51 from 90 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 14961.529411 with a remaining 3.9e-06.
