Let's divide 51961370 by 171
We're looking to find how many times 171 goes into 51961370.

Advancing to step 1:
When dividing 5 by 171, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 171

Let's proceed to step 2:
When dividing 51 by 171, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 171

Let's proceed to step 3:
The number 171 fits into 519 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 513 away from 519, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 171

Advancing to step 4:
The number 171 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 30.0
Subtracting 0 from 66 leaves us with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 171

Step 5:
171 goes into 661 3 times with a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
Subtracting 513 from 661 leaves us with 148.
Include the next digit (3) from the dividend after 148, then repeat: 1483 / 171

Let's proceed to step 6:
1483 divided by 171 is 8 with a remainder of 115.
The next digit of our result is 8. 
Result so far: 3038.0
If we take 1368 away from 1483, we end up with 115.
Append the next digit (7) from the dividend to 115 and continue with: 1157 / 171

Step 7:
When dividing 1157 by 171, we get 6 with a remainder of 131.
Use 6 as the next digit of our solution. 
Result so far: 30386.0
The remainder is 131 after subtracting 1026 from 1157.
Include the next digit (0) from the dividend after 131, then repeat: 1310 / 171

On to step 8:
171 goes into 1310 7 times with a remainder of 113.
Put 7 as the next digit of the answer. 
Result so far: 303867.0
The remainder is 113 after subtracting 1197 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
When dividing 1130 by 171, we get 6 with a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 303867.6
Deduct 1026 from 1130 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 10:
When dividing 1040 by 171, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 303867.66
Deduct 1026 from 1040 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 303867.66, and the remainder is 0.014.
