We're dividing 51971561 by 762 
We want to figure out the number of times 51971561 can be divided by 762.

On to step 1:
If we divide 5 by 762, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 762

On to step 2:
If we divide 51 by 762, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 762

Advancing to step 3:
519 divided by 762 is 0 with a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 519, we end up with 519.
Take the next digit (7) from the dividend and append it to 519, then repeat: 5197 / 762

Let's proceed to step 4:
762 can be fit into 5197 6 times, resulting in a remainder of 625.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 4572 from 5197 and we're left with 625.
Bring next digit (1) of the dividend behind the 625 and repeat the process: 6251 / 762

Let's proceed to step 5:
If we divide 6251 by 762, we get 8 and a remainder of 155.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 6096 from 6251 leaves us with 155.
Bring next digit (5) of the dividend behind the 155 and repeat the process: 1555 / 762

Step 6:
762 goes into 1555 2 times with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 682.0
If we take 1524 away from 1555, we end up with 31.
Grab the next digit (6) from the dividend, add it to 31, then carry on: 316 / 762

Let's proceed to step 7:
762 can be fit into 316 0 times, resulting in a remainder of 316.
Write down 0 as next digit of the result. 
Result so far: 6820.0
Deduct 0 from 316 and we're left with 316.
Append the next digit (1) from the dividend to 316 and continue with: 3161 / 762

Advancing to step 8:
3161 divided by 762 is 4 with a remainder of 113.
The number 4 becomes the next digit in our result. 
Result so far: 68204.0
If we take 3048 away from 3161, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
The number 762 fits into 1130 1 times, leaving a remainder of 368.
The next digit of our result is 1. 
Result so far: 68204.1
Subtract 762 from 1130 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 10:
762 goes into 3680 4 times with a remainder of 632.
Put 4 as the next digit of the answer. 
Result so far: 68204.14
Subtracting 3048 from 3680 leaves us with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
762 goes into 6320 8 times with a remainder of 224.
Use 8 as the next digit of our solution. 
Result so far: 68204.148
The remainder is 224 after subtracting 6096 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 12:
2240 divided by 762 is 2 with a remainder of 716.
The next digit of our result is 2. 
Result so far: 68204.1482
Subtracting 1524 from 2240 leaves us with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

On to step 13:
The number 762 fits into 7160 9 times, leaving a remainder of 302.
Record the quotient 9 as the next digit in the result. 
Result so far: 68204.14829
The remainder is 302 after subtracting 6858 from 7160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 14:
When dividing 3020 by 762, we get 3 with a remainder of 734.
The number 3 becomes the next digit in our result. 
Result so far: 68204.148293
If we take 2286 away from 3020, we end up with 734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7340, and continue the process.

Step 15:
7340 divided by 762 is 9 with a remainder of 482.
Use 9 as the next digit of our solution. 
Result so far: 68204.1482939
Deduct 6858 from 7340 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 16:
When dividing 4820 by 762, we get 6 with a remainder of 248.
Write down 6 as next digit of the result. 
Result so far: 68204.14829396
Subtracting 4572 from 4820 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final result is 68204.14829396 with a remainder of 2.48e-07.
