51600986 divided by 770 
We want to figure out the number of times 51600986 can be divided by 770.

Advancing to step 1:
When dividing 5 by 770, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 770

Step 2:
770 goes into 51 0 times with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 770

Moving on to step 3:
When dividing 516 by 770, we get 0 with a remainder of 516.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Fetch the next digit (0) from the dividend, attach it to 516 and continue: 5160 / 770

Let's proceed to step 4:
The number 770 fits into 5160 6 times, leaving a remainder of 540.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 540 after subtracting 4620 from 5160.
Fetch the next digit (0) from the dividend, attach it to 540 and continue: 5400 / 770

Let's proceed to step 5:
If we divide 5400 by 770, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 67.0
The remainder is 10 after subtracting 5390 from 5400.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 770

Moving on to step 6:
If we divide 109 by 770, we get 0 and a remainder of 109.
The number 0 becomes the next digit in our result. 
Result so far: 670.0
Subtract 0 from 109 to get 109.
Include the next digit (8) from the dividend after 109, then repeat: 1098 / 770

Step 7:
770 goes into 1098 1 times with a remainder of 328.
Put 1 as the next digit of the answer. 
Result so far: 6701.0
If we take 770 away from 1098, we end up with 328.
Append the next digit (6) from the dividend to 328 and continue with: 3286 / 770

Moving on to step 8:
770 goes into 3286 4 times with a remainder of 206.
The next digit of our result is 4. 
Result so far: 67014.0
If we take 3080 away from 3286, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 9:
When dividing 2060 by 770, we get 2 with a remainder of 520.
Put 2 as the next digit of the answer. 
Result so far: 67014.2
Deduct 1540 from 2060 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 10:
When dividing 5200 by 770, we get 6 with a remainder of 580.
The next digit of our result is 6. 
Result so far: 67014.26
Deduct 4620 from 5200 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 11:
If we divide 5800 by 770, we get 7 and a remainder of 410.
Record the quotient 7 as the next digit in the result. 
Result so far: 67014.267
Subtracting 5390 from 5800 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 12:
770 can be fit into 4100 5 times, resulting in a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 67014.2675
Subtracting 3850 from 4100 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 13:
When dividing 2500 by 770, we get 3 with a remainder of 190.
The next digit of our result is 3. 
Result so far: 67014.26753
Deduct 2310 from 2500 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 14:
The number 770 fits into 1900 2 times, leaving a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 67014.267532
The remainder is 360 after subtracting 1540 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
When dividing 3600 by 770, we get 4 with a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 67014.2675324
If we take 3080 away from 3600, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
770 goes into 5200 6 times with a remainder of 580.
The next digit of our result is 6. 
Result so far: 67014.26753246
The remainder is 580 after subtracting 4620 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 67014.26753246 with a remainder of 5.8e-07.
