77381001 ÷ 149 
We want to divide 77381001 by 149.

On to step 1:
The number 149 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 149

Let's proceed to step 2:
The number 149 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 149

Going ahead to step 3:
773 divided by 149 is 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 745 from 773 to get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 149

On to step 4:
The number 149 fits into 288 1 times, leaving a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 139 after subtracting 149 from 288.
Grab the next digit (1) from the dividend, add it to 139, then carry on: 1391 / 149

Advancing to step 5:
149 can be fit into 1391 9 times, resulting in a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 519.0
Deduct 1341 from 1391 and we're left with 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 149

Let's proceed to step 6:
149 goes into 500 3 times with a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 5193.0
If we take 447 away from 500, we end up with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 149

Let's proceed to step 7:
149 can be fit into 530 3 times, resulting in a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 51933.0
Deduct 447 from 530 and we're left with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 149

Advancing to step 8:
If we divide 831 by 149, we get 5 and a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 519335.0
Deduct 745 from 831 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
149 goes into 860 5 times with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 519335.5
Deduct 745 from 860 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 10:
1150 divided by 149 is 7 with a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 519335.57
If we subtract 1043 from 1150, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 11:
When dividing 1070 by 149, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 519335.577
Deduct 1043 from 1070 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 519335.577 with a remaining 0.0027.
