We look at the division of 51188598 by 307 
Our goal is to divide 51188598 by 307.

Step 1:
If we divide 5 by 307, we get 0 and 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.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 307

Advancing to step 2:
The number 307 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 307

Moving on to step 3:
307 goes into 511 1 times with a remainder of 204.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 307 from 511 and we're left with 204.
Bring next digit (8) of the dividend behind the 204 and repeat the process: 2048 / 307

On to step 4:
When dividing 2048 by 307, we get 6 with a remainder of 206.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 1842 from 2048 and we're left with 206.
Bring next digit (8) of the dividend behind the 206 and repeat the process: 2068 / 307

On to step 5:
If we divide 2068 by 307, we get 6 and a remainder of 226.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
The remainder is 226 after subtracting 1842 from 2068.
Fetch the next digit (5) from the dividend, attach it to 226 and continue: 2265 / 307

Step 6:
The number 307 fits into 2265 7 times, leaving a remainder of 116.
Write down 7 as next digit of the result. 
Result so far: 1667.0
If we take 2149 away from 2265, we end up with 116.
Append the next digit (9) from the dividend to 116 and continue with: 1169 / 307

On to step 7:
If we divide 1169 by 307, we get 3 and a remainder of 248.
The next digit of our result is 3. 
Result so far: 16673.0
Subtracting 921 from 1169 leaves us with 248.
Take the next digit (8) from the dividend and append it to 248, then repeat: 2488 / 307

Step 8:
2488 divided by 307 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 166738.0
Deduct 2456 from 2488 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
The number 307 fits into 320 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 166738.1
Subtract 307 from 320 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
If we divide 130 by 307, we get 0 and a remainder of 130.
The next digit of our result is 0. 
Result so far: 166738.1
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
When dividing 1300 by 307, we get 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 166738.104
Subtracting 1228 from 1300 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 12:
720 divided by 307 is 2 with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 166738.1042
If we take 614 away from 720, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 13:
307 can be fit into 1060 3 times, resulting in a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 166738.10423
Subtract 921 from 1060 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 14:
The number 307 fits into 1390 4 times, leaving a remainder of 162.
The next digit of our result is 4. 
Result so far: 166738.104234
If we subtract 1228 from 1390, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 15:
1620 divided by 307 is 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 166738.1042345
If we subtract 1535 from 1620, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 16:
307 goes into 850 2 times with a remainder of 236.
Record the quotient 2 as the next digit in the result. 
Result so far: 166738.10423452
Subtract 614 from 850 to get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 166738.10423452 with a remaining 2.36e-07.
