51615391 divided by 850 
We want to divide 51615391 by 850.

Going ahead to step 1:
5 divided by 850 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 850

Moving on to step 2:
850 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.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 850

Going ahead to step 3:
When dividing 516 by 850, we get 0 with a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 516 after subtracting 0 from 516.
Grab the next digit (1) from the dividend, add it to 516, then carry on: 5161 / 850

Advancing to step 4:
When dividing 5161 by 850, we get 6 with a remainder of 61.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 5100 from 5161 to get 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 850

Advancing to step 5:
The number 850 fits into 615 0 times, leaving a remainder of 615.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtract 0 from 615 to get 615.
Bring next digit (3) of the dividend behind the 615 and repeat the process: 6153 / 850

Step 6:
6153 divided by 850 is 7 with a remainder of 203.
The next digit of our result is 7. 
Result so far: 607.0
Subtracting 5950 from 6153 leaves us with 203.
Fetch the next digit (9) from the dividend, attach it to 203 and continue: 2039 / 850

Moving on to step 7:
850 can be fit into 2039 2 times, resulting in a remainder of 339.
Record the quotient 2 as the next digit in the result. 
Result so far: 6072.0
The remainder is 339 after subtracting 1700 from 2039.
Grab the next digit (1) from the dividend, add it to 339, then carry on: 3391 / 850

Step 8:
The number 850 fits into 3391 3 times, leaving a remainder of 841.
Write down 3 as next digit of the result. 
Result so far: 60723.0
Subtracting 2550 from 3391 leaves us with 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Let's proceed to step 9:
If we divide 8410 by 850, we get 9 and a remainder of 760.
The number 9 becomes the next digit in our result. 
Result so far: 60723.9
If we subtract 7650 from 8410, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Going ahead to step 10:
850 goes into 7600 8 times with a remainder of 800.
Put 8 as the next digit of the answer. 
Result so far: 60723.98
If we subtract 6800 from 7600, we get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 11:
850 can be fit into 8000 9 times, resulting in a remainder of 350.
The number 9 becomes the next digit in our result. 
Result so far: 60723.989
If we subtract 7650 from 8000, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
The number 850 fits into 3500 4 times, leaving a remainder of 100.
Write down 4 as next digit of the result. 
Result so far: 60723.9894
If we subtract 3400 from 3500, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 13:
1000 divided by 850 is 1 with a remainder of 150.
Write down 1 as next digit of the result. 
Result so far: 60723.98941
If we take 850 away from 1000, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 14:
If we divide 1500 by 850, we get 1 and a remainder of 650.
Put 1 as the next digit of the answer. 
Result so far: 60723.989411
If we take 850 away from 1500, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final outcome is 60723.989411, with a leftover of 6.5e-05.
