We look at the division of 74778528 by 637 
We want to divide 74778528 by 637.

Step 1:
If we divide 7 by 637, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 637

Moving on to step 2:
637 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 637

On to step 3:
When dividing 747 by 637, we get 1 with a remainder of 110.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 637 from 747 and we're left with 110.
Grab the next digit (7) from the dividend, add it to 110, then carry on: 1107 / 637

Advancing to step 4:
637 goes into 1107 1 times with a remainder of 470.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 637 from 1107 leaves us with 470.
Bring next digit (8) of the dividend behind the 470 and repeat the process: 4708 / 637

Step 5:
If we divide 4708 by 637, we get 7 and a remainder of 249.
The next digit of our result is 7. 
Result so far: 117.0
Subtract 4459 from 4708 to get 249.
Include the next digit (5) from the dividend after 249, then repeat: 2495 / 637

Let's proceed to step 6:
637 goes into 2495 3 times with a remainder of 584.
Use 3 as the next digit of our solution. 
Result so far: 1173.0
Subtracting 1911 from 2495 leaves us with 584.
Append the next digit (2) from the dividend to 584 and continue with: 5842 / 637

Moving on to step 7:
When dividing 5842 by 637, we get 9 with a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 11739.0
Deduct 5733 from 5842 and we're left with 109.
Include the next digit (8) from the dividend after 109, then repeat: 1098 / 637

On to step 8:
When dividing 1098 by 637, we get 1 with a remainder of 461.
Put 1 as the next digit of the answer. 
Result so far: 117391.0
The remainder is 461 after subtracting 637 from 1098.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Going ahead to step 9:
637 goes into 4610 7 times with a remainder of 151.
The number 7 becomes the next digit in our result. 
Result so far: 117391.7
The remainder is 151 after subtracting 4459 from 4610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 10:
637 goes into 1510 2 times with a remainder of 236.
Write down 2 as next digit of the result. 
Result so far: 117391.72
Subtracting 1274 from 1510 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
If we divide 2360 by 637, we get 3 and a remainder of 449.
The next digit of our result is 3. 
Result so far: 117391.723
Deduct 1911 from 2360 and we're left with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Step 12:
The number 637 fits into 4490 7 times, leaving a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 117391.7237
The remainder is 31 after subtracting 4459 from 4490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
When dividing 310 by 637, we get 0 with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 117391.7237
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 14:
The number 637 fits into 3100 4 times, leaving a remainder of 552.
Record the quotient 4 as the next digit in the result. 
Result so far: 117391.723704
Subtracting 2548 from 3100 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 15:
When dividing 5520 by 637, we get 8 with a remainder of 424.
The next digit of our result is 8. 
Result so far: 117391.7237048
If we take 5096 away from 5520, we end up with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 16:
637 can be fit into 4240 6 times, resulting in a remainder of 418.
Put 6 as the next digit of the answer. 
Result so far: 117391.72370486
Subtracting 3822 from 4240 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 117391.72370486, with a leftover of 4.18e-07.
