We look at the division of 51388644 by 607 
We're looking to find how many times 607 goes into 51388644.

On to step 1:
607 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 607

Moving on to step 2:
The number 607 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 607

Going ahead to step 3:
607 goes into 513 0 times with a remainder of 513.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 513 after subtracting 0 from 513.
Bring next digit (8) of the dividend behind the 513 and repeat the process: 5138 / 607

Advancing to step 4:
607 can be fit into 5138 8 times, resulting in a remainder of 282.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 282 after subtracting 4856 from 5138.
Grab the next digit (8) from the dividend, add it to 282, then carry on: 2828 / 607

Advancing to step 5:
607 goes into 2828 4 times with a remainder of 400.
The next digit of our result is 4. 
Result so far: 84.0
Subtracting 2428 from 2828 leaves us with 400.
Grab the next digit (6) from the dividend, add it to 400, then carry on: 4006 / 607

Moving on to step 6:
4006 divided by 607 is 6 with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 846.0
Subtracting 3642 from 4006 leaves us with 364.
Append the next digit (4) from the dividend to 364 and continue with: 3644 / 607

Moving on to step 7:
The number 607 fits into 3644 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 8466.0
Deduct 3642 from 3644 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 607

On to step 8:
When dividing 24 by 607, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 84660.0
If we subtract 0 from 24, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 607, we get 0 with a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 84660.0
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
If we divide 2400 by 607, we get 3 and a remainder of 579.
The next digit of our result is 3. 
Result so far: 84660.03
Deduct 1821 from 2400 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 11:
607 can be fit into 5790 9 times, resulting in a remainder of 327.
The next digit of our result is 9. 
Result so far: 84660.039
Deduct 5463 from 5790 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 12:
When dividing 3270 by 607, we get 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 84660.0395
If we subtract 3035 from 3270, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 13:
If we divide 2350 by 607, we get 3 and a remainder of 529.
Use 3 as the next digit of our solution. 
Result so far: 84660.03953
If we subtract 1821 from 2350, we get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 14:
5290 divided by 607 is 8 with a remainder of 434.
The next digit of our result is 8. 
Result so far: 84660.039538
The remainder is 434 after subtracting 4856 from 5290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 15:
If we divide 4340 by 607, we get 7 and a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 84660.0395387
If we subtract 4249 from 4340, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 16:
607 can be fit into 910 1 times, resulting in a remainder of 303.
Write down 1 as next digit of the result. 
Result so far: 84660.03953871
Deduct 607 from 910 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final result is 84660.03953871 with a remainder of 3.03e-07.
