We divide 79945321 by 138
We're looking to find how many times 138 goes into 79945321.

On to step 1:
When dividing 7 by 138, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 138

Let's proceed to step 2:
79 divided by 138 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (9) of the dividend behind the 79 and repeat the process: 799 / 138

Step 3:
138 can be fit into 799 5 times, resulting in a remainder of 109.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 690 from 799, we get 109.
Bring next digit (4) of the dividend behind the 109 and repeat the process: 1094 / 138

Moving on to step 4:
If we divide 1094 by 138, we get 7 and a remainder of 128.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we take 966 away from 1094, we end up with 128.
Append the next digit (5) from the dividend to 128 and continue with: 1285 / 138

Advancing to step 5:
When dividing 1285 by 138, we get 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 579.0
Subtract 1242 from 1285 to get 43.
Take the next digit (3) from the dividend and append it to 43, then repeat: 433 / 138

Step 6:
The number 138 fits into 433 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 5793.0
If we subtract 414 from 433, we get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 138

Going ahead to step 7:
If we divide 192 by 138, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 57931.0
Deduct 138 from 192 and we're left with 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 138

On to step 8:
138 goes into 541 3 times with a remainder of 127.
The next digit of our result is 3. 
Result so far: 579313.0
Subtracting 414 from 541 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 9:
When dividing 1270 by 138, we get 9 with a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 579313.9
The remainder is 28 after subtracting 1242 from 1270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
280 divided by 138 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 579313.92
Subtract 276 from 280 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
138 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 579313.92
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
138 goes into 400 2 times with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 579313.9202
Subtract 276 from 400 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 13:
138 can be fit into 1240 8 times, resulting in a remainder of 136.
Record the quotient 8 as the next digit in the result. 
Result so far: 579313.92028
The remainder is 136 after subtracting 1104 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Moving on to step 14:
The number 138 fits into 1360 9 times, leaving a remainder of 118.
The next digit of our result is 9. 
Result so far: 579313.920289
The remainder is 118 after subtracting 1242 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 15:
When dividing 1180 by 138, we get 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 579313.9202898
Deduct 1104 from 1180 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 16:
760 divided by 138 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 579313.92028985
If we subtract 690 from 760, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 579313.92028985 and a remainder of 7e-08.
