51037753 divided by 851 
We want to figure out the number of times 51037753 can be divided by 851.

On to step 1:
5 divided by 851 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 851

Step 2:
The number 851 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 851

On to step 3:
510 divided by 851 is 0 with a remainder of 510.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 510 and we're left with 510.
Fetch the next digit (3) from the dividend, attach it to 510 and continue: 5103 / 851

Let's proceed to step 4:
851 goes into 5103 5 times with a remainder of 848.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4255 from 5103 to get 848.
Bring next digit (7) of the dividend behind the 848 and repeat the process: 8487 / 851

Advancing to step 5:
851 can be fit into 8487 9 times, resulting in a remainder of 828.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 7659 from 8487, we get 828.
Bring next digit (7) of the dividend behind the 828 and repeat the process: 8287 / 851

Moving on to step 6:
The number 851 fits into 8287 9 times, leaving a remainder of 628.
The number 9 becomes the next digit in our result. 
Result so far: 599.0
Subtract 7659 from 8287 to get 628.
Grab the next digit (5) from the dividend, add it to 628, then carry on: 6285 / 851

Advancing to step 7:
6285 divided by 851 is 7 with a remainder of 328.
Write down 7 as next digit of the result. 
Result so far: 5997.0
Subtracting 5957 from 6285 leaves us with 328.
Bring next digit (3) of the dividend behind the 328 and repeat the process: 3283 / 851

Step 8:
When dividing 3283 by 851, we get 3 with a remainder of 730.
Write down 3 as next digit of the result. 
Result so far: 59973.0
Subtracting 2553 from 3283 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Let's proceed to step 9:
When dividing 7300 by 851, we get 8 with a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 59973.8
If we subtract 6808 from 7300, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 10:
4920 divided by 851 is 5 with a remainder of 665.
Put 5 as the next digit of the answer. 
Result so far: 59973.85
Subtracting 4255 from 4920 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Going ahead to step 11:
If we divide 6650 by 851, we get 7 and a remainder of 693.
Put 7 as the next digit of the answer. 
Result so far: 59973.857
If we take 5957 away from 6650, we end up with 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Advancing to step 12:
The number 851 fits into 6930 8 times, leaving a remainder of 122.
The next digit of our result is 8. 
Result so far: 59973.8578
Subtract 6808 from 6930 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 13:
851 goes into 1220 1 times with a remainder of 369.
The next digit of our result is 1. 
Result so far: 59973.85781
The remainder is 369 after subtracting 851 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Advancing to step 14:
The number 851 fits into 3690 4 times, leaving a remainder of 286.
The next digit of our result is 4. 
Result so far: 59973.857814
Deduct 3404 from 3690 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 15:
When dividing 2860 by 851, we get 3 with a remainder of 307.
The number 3 becomes the next digit in our result. 
Result so far: 59973.8578143
Deduct 2553 from 2860 and we're left with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 16:
851 can be fit into 3070 3 times, resulting in a remainder of 517.
Use 3 as the next digit of our solution. 
Result so far: 59973.85781433
The remainder is 517 after subtracting 2553 from 3070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

The final result is 59973.85781433 with a remainder of 5.17e-07.
