We look at the division of 74745536 by 581 
We're looking to find how many times 581 goes into 74745536.

Advancing to step 1:
If we divide 7 by 581, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 581

Going ahead to step 2:
581 can be fit into 74 0 times, resulting in a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 581

Step 3:
If we divide 747 by 581, we get 1 and a remainder of 166.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 581 from 747, we get 166.
Grab the next digit (4) from the dividend, add it to 166, then carry on: 1664 / 581

Moving on to step 4:
If we divide 1664 by 581, we get 2 and a remainder of 502.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1162 from 1664, we get 502.
Grab the next digit (5) from the dividend, add it to 502, then carry on: 5025 / 581

On to step 5:
The number 581 fits into 5025 8 times, leaving a remainder of 377.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 4648 from 5025 leaves us with 377.
Include the next digit (5) from the dividend after 377, then repeat: 3775 / 581

Going ahead to step 6:
The number 581 fits into 3775 6 times, leaving a remainder of 289.
Write down 6 as next digit of the result. 
Result so far: 1286.0
The remainder is 289 after subtracting 3486 from 3775.
Fetch the next digit (3) from the dividend, attach it to 289 and continue: 2893 / 581

On to step 7:
The number 581 fits into 2893 4 times, leaving a remainder of 569.
Write down 4 as next digit of the result. 
Result so far: 12864.0
The remainder is 569 after subtracting 2324 from 2893.
Append the next digit (6) from the dividend to 569 and continue with: 5696 / 581

Moving on to step 8:
If we divide 5696 by 581, we get 9 and a remainder of 467.
Record the quotient 9 as the next digit in the result. 
Result so far: 128649.0
Deduct 5229 from 5696 and we're left with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 9:
581 can be fit into 4670 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 128649.8
Subtracting 4648 from 4670 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 581, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 128649.8
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 11:
The number 581 fits into 2200 3 times, leaving a remainder of 457.
Record the quotient 3 as the next digit in the result. 
Result so far: 128649.803
Subtracting 1743 from 2200 leaves us with 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 12:
When dividing 4570 by 581, we get 7 with a remainder of 503.
Record the quotient 7 as the next digit in the result. 
Result so far: 128649.8037
Deduct 4067 from 4570 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 13:
The number 581 fits into 5030 8 times, leaving a remainder of 382.
Write down 8 as next digit of the result. 
Result so far: 128649.80378
Subtract 4648 from 5030 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 14:
581 goes into 3820 6 times with a remainder of 334.
The next digit of our result is 6. 
Result so far: 128649.803786
Subtracting 3486 from 3820 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 15:
When dividing 3340 by 581, we get 5 with a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 128649.8037865
Deduct 2905 from 3340 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 16:
581 can be fit into 4350 7 times, resulting in a remainder of 283.
Record the quotient 7 as the next digit in the result. 
Result so far: 128649.80378657
Subtracting 4067 from 4350 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final result is 128649.80378657 with a remainder of 2.83e-07.
