Let's divide 79973218 by 139
Our goal is to divide 79973218 by 139.

Going ahead to step 1:
139 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 139

Going ahead to step 2:
When dividing 79 by 139, we get 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Fetch the next digit (9) from the dividend, attach it to 79 and continue: 799 / 139

Moving on to step 3:
799 divided by 139 is 5 with a remainder of 104.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 695 away from 799, we end up with 104.
Append the next digit (7) from the dividend to 104 and continue with: 1047 / 139

Moving on to step 4:
When dividing 1047 by 139, we get 7 with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we take 973 away from 1047, we end up with 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 139

Going ahead to step 5:
If we divide 743 by 139, we get 5 and a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 575.0
Subtract 695 from 743 to get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 139

Step 6:
139 goes into 482 3 times with a remainder of 65.
Put 3 as the next digit of the answer. 
Result so far: 5753.0
Deduct 417 from 482 and we're left with 65.
Take the next digit (1) from the dividend and append it to 65, then repeat: 651 / 139

Going ahead to step 7:
139 goes into 651 4 times with a remainder of 95.
Use 4 as the next digit of our solution. 
Result so far: 57534.0
If we take 556 away from 651, we end up with 95.
Append the next digit (8) from the dividend to 95 and continue with: 958 / 139

Moving on to step 8:
139 goes into 958 6 times with a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 575346.0
Subtracting 834 from 958 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 9:
If we divide 1240 by 139, we get 8 and a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 575346.8
Subtract 1112 from 1240 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 10:
139 goes into 1280 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 575346.89
Deduct 1251 from 1280 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
290 divided by 139 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 575346.892
If we subtract 278 from 290, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
When dividing 120 by 139, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 575346.892
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 13:
The number 139 fits into 1200 8 times, leaving a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 575346.89208
Subtract 1112 from 1200 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
139 can be fit into 880 6 times, resulting in a remainder of 46.
The next digit of our result is 6. 
Result so far: 575346.892086
If we take 834 away from 880, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 15:
If we divide 460 by 139, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 575346.8920863
Subtract 417 from 460 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 16:
When dividing 430 by 139, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 575346.89208633
Subtracting 417 from 430 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 575346.89208633, with a leftover of 1.3e-08.
